  1. CC,

     

    Your photo is one of the best I have seen of Bangor to date. There are very few which show the right edge of the goods yard which this photos does. I am also interested in the actual traffic sitting in the yard. It shows a range of vehicle types and goods loads, and most importantly shows their position within the yard. Even the goods sitting on the ground on the right of the photo provide insight into the operation of the yard. Being in colour will assist with developing the relevant colour scheme.

     

    This photo will obviously be a key component in my modelling the Bangor goods yard. Thank you very much for contributing your own photo to the layout research and design. I am interested in any other photos of the north Welsh coast area.

     

    I have not yet sorted out the freight operation in the 60s on the Chester Holyhead line. Do you have any material on this. I have tried a number of books and sourced some material. The thread at entry number no 106 contains detail of a selection of freight transported on the line. Any other info would be welcome.

     

    I am still working out the power, track detection, electronics and other technical requirements before laying track. I have 2 houses in Brisbane to visit over the next 2 days to assist with this issue. Many emails and decisions are yet to be made. I have a 5 amp NCE controller and couple of hand sets, but the ret has yet to be decided.

     

    I would love to see any photos of your layout.

     

    Once again thank you for your assistance it is greatly appreciated.

     

    Regards,

  2. LAYOUT DEVELOPMENTS

     

    I have spent the weekend marking various structures on the boards. These includes some of the roads, Conwy station, the rest of the medieval town, ditch road foot path and grassed area. In addition I have sorted the power districts and sub power districts. I now need to determine what areas I need to divide for track detection, how to facilitate the track detection, how to automate the point control and how to tie all of these issues into a computer. I have found the marking up a lot easier than the electronics, which I have found very difficult.

     

    I will need to send many more email before these issues have been finalised.

     

    Regards,

    LAYOUT DEVELOPMENTS OR LACK THEREOF

     

    I have spent the last 3 days trying to get an idea on the wiring for the layout. This has included the Power district and sub district layout (use boosters for the districts and circuit breakers for the sub districts. Once I have sorted these I need to determine how I am going to manage track detection and point switching, although I am only required to prepare for the Conwy section immediately, I need a plan for the whole layout. I tried to put a question in the DCC question area of RM web but got no response. A little disappointing. I have sent a colour coded track plan to some of the guys in a couple of DCC forums showing my proposed power districts and sub districts. It is a slow process with most of them in the US or UK. I need to ensure my wiring plan is fool proof and without the required knowledge need to rely on the generosity of others for assistance.

     

    I certainly have a much better idea than I did 4 days ago, but more to understand. For instance I have yet to understand the purpose of a DPDT switch for a sub district when it runs through a circuit breaker. If anyone knows the answer I am interested.

  4. LAYOUT DEVELOPMENT

     

    I have had to wait for further developments pending the checking of my track positioning by a local modelling expert. With my lack of experience I need to ensure the track is properly placed prior to securing it. It will be checked thisThursday.

     

    Once checked the plan is to mark the track edges with a permanent marker. Take a trace of the track using tracing paper. Mark the cork sheeting up using the tracing paper trace. Cut the cork to the track layout and stick to the base boards. Is this a reasonable method or is there a shorter equally accurate means.

     

    Regards,

  5. WELSH DRAGON RAIL DEVELOPMENTS

     

    I have been placing track on the main line and goods areas for Conwy. Not sure what the next stage is but I think I will mark the position of all pieces of tack, label the spot and then cut cork to fit the track plan. Please advise if this is the right process.

     

    Once I have cut and stuck the cork I can then paint it to reduce the risk of moisture expansion.

  6. Beast,

     

    Thanks very much for the photo. It is first class and not one I have seen before. I shall definitely use it when I move around to the next station.

     

    Once again thanks very much. All photos and comments are appreciated, and really make the layout much easier to model.

     

    I spent to day drawing on the layout a 100 ml grid to replicate the plan grid. It took 3 hours but will make the layout placement much easier.

  7. WIRING GUIDANCE.

     

    I am now starting to venture into unchartered territory. Namely laying the track and wiring. I believe I shall be reasonably OK with some local assistance in laying the track. Wiring for DCC is another matter and one which I am seeking readers contribution. 

     

    I am definitely doing a DCC layout so that is the first limitation. I intend to make the layout both controllable via a computer or virtually manual, depending on the number of persons involved in the session. I need to do this because of the size. I am unsure how the layout should be computerised.  From my reading I understand that a DCC layout can be divided into power districts with boosters from the main controller laid in series. Power buses from each booster and power source then goes to the track from each booster. Again I am confident with these concepts. I can see possibly 4 power districts. The power districts correspond to the 3 scenic areas on the top level. You may wish to refer to page 2 with the complete plan. The power districts will therefore be divided into Conwy, Penmaenmawr and Bangor. I may then need 1 or 2 for the hidden area. No problem so far. There may however be some difficulty in fault finding in such large areas, and that these power areas should be further divided into manageable sections.

     

    I understand that circuit breakers can be installed between the power booster and the track. These can have between 1 to 4 outlets which can then be used to create additional isolated areas, with an additional isolated area for each circuit breaker output. Am I on the right track here. In looking at Conwy I thought I would use 4 circuit breakers. 1 to cover the area on the right of the layout from the scenic break above Bangor to the left side of the tubular bridge across the other side of the river Conwy. The next would cover from that end of the tubular bridge to half way between that point and Conwy station on the left of the  layout. The next covers from half way between the tubular bridge to the scenic divider below Conwy station. The 4th would cover the goods are above the mainline next to the town of Conwy. Do you think this is sufficient circuit breakers to make fault finding manageable. The up and down lines would be on the same circuit breakers for each section.

     

    I have not yet decided how to create sections for the circuit breakers for Penmaenmawr or Bangor, but am interested in others views, but I am particularly keen to sort out Conwy. To remind you the full plan is on page 2.

     

    Does anyone know if the circuit breaker scan be used for track detection. How do you install more detailed track detection at a reasonable cost.

     

    If those following this thread could assist with any comments it would be greatly appreciated.

  8. Dear Artizan,

     

    Thanks for the advice. Painting has been conducted at a furious pace! Everything has been painted including myself on some occasions.

     

    Jennarivo,

     

    Thanks for the encouraging comments. They help maintain motivation in the face of a daunting task! I did a check list of vehicles I would like and they number 70.

  9. Anthony,

     

    You might find that with a layout that big, you'll welcome the noise so you can tell where the trains are !!

     

    Stu

    Stu I intend to sound chip at least a good number of the locos so hearing them should be no problem. The issue is does the enamel paint protect from moisture better than the acrylic when applied to the cork and ply base. I suppose it must be at least as good or maybe better so that is the option I should use ie enamel.

     

    Happy for more comments though.

  10. TO USE ENAMEL OR ACRYLIC PAINT ON THE TRACK AREA

     

    Another query to those following the thread. Do readers believe modern acrylic paint is sufficiently resistant to water and the atmosphere given I live in Brisbane for the track area. Alternatively is the opinion enamel oil based paint should be used on the track area. I am obviously planning on securing the ballast using water, PVA glue and a drop of dish washing liquid. The enamel may provide more protection from the water. There have been occasions in Australia where the cork ballast has become water logged and expanded,  ruining the track laying. 

     

    What is the general opinion?

     

    Regards,

    Horizontal surfaces on the scenic area are complete! A productive day with finishing off the last of the horizontal surfaces on the scenic track and much painting.

     

    Photos are below. I hope you enjoy them. The rake is the Irish Mail minus the 2 sleepers which I have not been able to purchase as yet. Eventually I should be good to get them.

  12. Dear Stu,

     

    In reply to your comment on the smallest house in Britain. I miss out modelling it by a house or two. The layout finishes just before that particular feature of Conwy. In N gauge it would be very small indeed.

     

    Dear Beast,

     

    Thanks for the help with the freight types. I have just ordered the book by Trefor Thompson on North Welsh Rail so will see what this has to offer. I shall keep your suggestion in mind.

     

    I did a fair amount of painting today, completing the priming of all boards on the layout, both on top and underneath. I have completed the top coat for the main line and the far west of the layout. This will enable me to mark the road just outside the medieval wall and to therefore work out how wide the long piece on elevated scenery over the top of the hidden track needs to be. Once I have completed the marking I can cut the last two small boards and on with the rest of the marking for all of Conwy. I have a full day free tomorrow.

     

    Keep the comments or suggestions coming if possible. Still interested in possible freight for the mail line. I have seen pictures of them on the line but believe it was in the 70s.

     

    Does anyone know if Class 37s ran on the north Welsh Coast mainline in the 60s?

     

    Regards,

  13. This is an interesting issue. As it is my intention to have a permanent vehicle attached to the tender. This will allow me to incorporate DCC sound and a speaker in at least a good proportion of the rakes within the 3rd vehicle. If I do this there is a need to have the first three elements of the train moved to the other end and in most cases the coach or brake at what has become the front of the train to the back. This means all other rake elements will be reversed. I have data on the majority of vehicles immemdiately behind the tender for a lot of rakes which ran on the Chester Holyhead kine in the 60s. In most cases this vehicle is a brake second, a full brake or a fitted van. There are the odd exceptions but generally I will be fairly right with one of these permanently attached. This may result in some slight variation in the return journey to the rake but modellers license will need to be employed to achieve sound.

     

    I have no issue in redesigning the hidden area as I have ony constucted up to the top of the grey operational area ie the main part of Conwy with only just incorporating part of the station. See the plan on page 2 of the blog to understand where I am at, the full plan is on that page I think. I shall need to think about the issue. The idea by Markus is certainly an option.

     

    I have alreadyt redesigned the hidden area of the layout recently incorporating the loops shown on the existing plan. I have been away interstate for 2 days but am now home and should fininsh the horizontal surfaces this week end. Next is drawing a 100ml grid to facilitate the drawing of the plan on the surface of the layout. The Any Rail computer program allows any size grid to be overlaid on the plan. I find 100 ml the best.

     

    I need tp purchase the book by Trefor Thompson which may assist with freight types. I shall also have a look at the other book recommendations above

    Thanks for all the comments they are great and assist me hugely!

     

     

    Regards,

  14. Stu and Grafarman, 

     

    I agree with yout conclusoins in regard to the turntable operation. I decided to put in the turntables proir to determining the composition of the rakes, which were in reverse order for the up and down lines. It appears from my reasearch that most involved the disconnection of the loco from front to back, thereby negating the need to turn the whole rake around. This the case where I have data for the 24 rakes (10 of which were DMUs , but I am likely to use a combination of half DMU half local subrurban coaches with steam locos as I have the suburban stock).  The data collected for the rest of the rakes shows they seem to have travelled only one way and then either travleed else where or were split up with other rakes. I am going to have to run these from their destination through the hidden track if I wish to remain true to the prorotype. It would there seem that the need for turntables may not be that necessary. I shall ponder this further. Either way I shall need cassettes or turntables. If turntables, they are likely to be rarely used as you have identified except as a storage means.

     

    If anyone has any detail on the freight carried on the Chester to Holyhead main line I would appreciate your comments.

     

     

     

    Regards,

  15. David,

     

    I have had difficulty with determining exact freight movements on the main line. Stewart Blencowe was recommended as a source of information. He does have some freight time tables which obviously provide timings for freight movement, but this data does not include the types of freight moved.

     

    I have a series of articles from a train mag which provides some freight types on the line including cattle, granite, domestic and gas coal, general merchandise, live stock, animal feed, implements, petrol and oil, timber an building materials, fish and mussel traffic, PO wagons, sheet open and ventilated vans, cattle vans, low sided wagons, drums on open wagons, open wagons, slate, railway ballast, road stone, dressed stone, concrete products, explosives, mining stores, steel vans, fertilizers, hay and fodder.

     

    If any one has more detail please let me know on the site.

     

    Thanks for the interest.

     

    Regards,

  16. Merf,

     

    I agree the number of Red/Cream coaches was certainly on the decline. I have looked at the Llandudno 69 web site and there are pictures of at least some so I can legitimately sprinkle a few through my rakes. I already have 15 or so and will use them throughout the 45 rakes I need to create. I have acquired about 5 Gresley SKs so will use them as well. Your comments are great thanks for contributing.

     

     

    David,

     

    The turn tables will remain in place as much as possible. I have sufficient clearance under the layout to turn them around as you can see by the radius ring. I shall have to be sparing with legs on the 2 boards above the turntables to allow the required clearance. The whole layout will lock in and be self supporting. I agree with 18 inches as a minimum. You have pretty much understood the means of using the turn tables.

     

    I shall try to remember to include the bus in all photos from now on as it provides a sense of scale as you said. I think the first one with the bus was by mistake but I liked it any way.

     

    Thank you for your comments they provide good feed back.

     

    The next large board has been fitted. Only two to go!

  17. WELSH DRAGON RAILWAY DEVELOPMENTS

     

    I managed to achieve laying a few more base boards but spent a long time working out the lower two boards to the west of Conwy where the old moat used to run.

     

    I took approx. 4 efforts to draw and finally cut these boards. The main issue was ensuring clearance between the lower level and the declining hidden track which does a 90 degree bend in this area. I have finally worked it out, attached the supporting structures (I had to replace these 3 times) cut and secured the boards. I only have one small and a larger board to fit which need to lift to give access to the hidden track. There is another board to fit which will be secured to the base boards.

     

    Photos with explanations are below.

    The new moat area which caused a lot of delay in deciding relative locations. The piece of paper in the middle of the photos is an N gauge scale plan of the station. To the left of the station are quite significant elevation changes which assist in hiding the hidden track

    The line of boards with the track on it is the main line track area. The board at the end of the track with the station plan has been given the final coat of paint. I have used an exterior acrylic. Are there any comments on this. Acrylic is easier to use but being exterior relatively hard wearing. I have chosen brown to blend in the scenery.

  18. Artizen,

     

    The turn tables will be on casters and can be moved to the outside of the layout or into the operational area giving hopefully good access.

     

    The advice I am seeking re clearance is what is a safe clearance between the bottom of the base board and the top of the turntable. I don't want to know the distance sufficient to put a hand in as this will not be sufficient to fix problems on the turntable. Given the "helix" style loops on either side of the table within the hidden area I can go as low as I like by adding additional loops. So my questions still stands what is an optimal height. Is 12 inches considered enough or should I go for 18 inches? Or is less enough?

     

    With all the expert modellers reading RM web I am sure there must be plenty of opinions. Please share them.

     

    Regards,

     

    Anthony Ashley

  19. Merf,

     

    I am modelling the 60s so the 4th bridge would have been there for some of this time but unsure how much. I prefer the 3 bridge look and will go with that. In regard top the Stanier coaches I have a fair number of them and the rakes are mixed Mk1s and Stanier in most cases. Given the number of coaches required I shall get more Staniers and Mk 1s.

     

    Thank you for your input as I was not on the mix but had the LMS coaches anyway.

     

    I spent most of today trying to work out the heights on the left side of Conwy while giving clearance to the hidden and declining track. It is a little complex but I have worked it out now. Should get more doen tomorrow with e public holiday.

     

    If any one can assist with a recommended clearance between the 4 foot wide turn tables and base of the boards I would appreciate the assistance.

     

     

    Regards,

  21. WELSH DRAGON RAILWAY A REALITY CHECK

     

    In answering the three entries above in order.

     

    I am a many generation Australian although my forebears were English on both sides of my family. My interest in the British railway system partly sprung for the locos belonging to my great uncle. I have also had a few trips to the UK and have really enjoyed the country and British history.

     

    My reason for modelling Conwy, Penmenmawr and Bangor are listed on the first page. In summary Conwy has fantastic scenery including the 12th century castle and medieval town and wall. Penmenmawr has a granite quarry with light rail, is a pretty sea side holiday town and has Pen-y-clip viaduct and the large mountain adjacent to it, which I shall model. Bangor is ideally placed with a substantial track infrastructure and rail facilities with a great location in a valley.

     

    The quote that this is my first layout is correct it is, but it may well be the only one I ever make. I was pleased with the ingenuity for the first layout, although it may not work, hence the requests for critical, incisive and informed comments! Estimated completion time is 25-20 years for the whole thing, although I may be quicker.

     

    Yes there is lots of room on the block, but the council are unlikely to approve another shed and the budget would not go that far!

  22. QUESTIONS ON THE WELSH DRAGON RAILWAY

    I have received the following three questions on the layout.

    For instance,
    (a) what is the distance between the lower edge of the upper baseboard
    supports and the track level of the lower deck?
    ( B) you mention a spiral - where is it located and does it in any way
    eliminate the two 'transition areas'? I interpret the two 'dots' in the diagram of the lower deck as being at the mid-points of the transition areas' - am I right?
    © where are the two 8 ft. turntables located? Are they replacements for
    what appear to be two traversers?

    For those who are confused by the plan the following is offered in answer to the above questions.

    1. The lower edge of the top section of the layout featuring Conwy is set at 45 inches above ground level. The frame work has a width of 65 ml. Therefore height above ground level is 45inches minus just over 2 inches or approx 43 inches. The hidden track plan has a series of purple or black lines. These show the layout board sizes I need to build. The top section constructed to date comprising the area above the operational area and featuring most of Conwy there is made up of, going from left to right a 6X6 foot board and two boards 5X6 feet each. The distance across is therefore 16 feet.

    In my most recent hidden track plan the sea areas finishes 10 feet down from the top of the layout on the edge of the second board down on the right side of the layout. Similarly the low flood plain to the south of Conwy just above the creek line extend to the edge of the second board on the left. All of this area is approx 43 inches above the ground from the bottom of the base board. There will be scenic divides between the second and third board from the top on either side of the layout. In fact there are two pairs of lines of hidden track at the top of the layout on the left. One joins into the transition area at the circle marked on the left of the layout at main line track height and the other continues down at a continuous 1:100 gradient to terminate at the turntable on the right. In summary the first three boards are already built and the next two, one on either side of the layout need to be at the same height to accommodate the sea on the right and the low flood plain in the vicinity of Conwy station ie 45 inches on the left side of the layout.

    I believe my next part of the layout is clever. Once I get to the third board from the top, on either side of the layout, my minimum height will rise to the actual main line track height ie 48 inches. In Conwy and nearly all the rest of the layout is at a height of 48 inches from ground level with a clearance taking into account the width of the base of approx 46 inches. With the scenic dividers in place I can therefore raise the height of the remainder of the layout to 48 inches. This will mean the use of less ply to create the elevations required, the hidden track going down to either turn table will suddenly be below the base board height or very close to it by raising the base boards by 3 inches. I shall need to create a narrow but long lower area to construct the sea at 45 inches elevation above the ground,down the left side of the layout(this may be detachable not sure yet). This also provides more distance between the bottom of the main layout and the two large turn tables.

    I think for my first layout this is a neat engineering solution as it minimises the amount of ply for the elevations required, minimises any cutting of the framework and supports to accommodate the lowering of the hidden track and provides more room for the turn tables.

    You will note that the hidden track has an entrance flap marked. This raising of the second board with be facilitated by a pivot point on the third board below the second board. I will use a rectangular metal frame with a handle sticking through the exterior of the middle of the second board, going from the front to back of the second base board. This will then be lifted and pivot over the third board to rest on 45 degree chocks secured to the third board on the top of the layout. The third board as indicated above will be 3 inches above the second, but if I cut the join between the two as a wedge shape and allow the support second board to pivot around the supporting metal with the handle, as it is lifted, this should work.

    2. The question about the distance between the lower edge of the base boards and the track level of the lower deck and the spirals are related. As stated above the hidden track around the top of the layout is at approx 45 inches or sea level. The sea wall on which Conwy is resting is 3 inches high. I have raised the northern section of the town of Conwy to create a larger distance between the top of the scenic area at the northern edge of the layout and the hidden track which goes underneath the town (the gap is about 6 inches). My plan is to use Perspex to protect this northern edge of the hidden track hinged to the top of the layout and hidden by the buildings of Conwy. Once the hidden track at the top of the layout bends from the east west direction to the south on the left of the layout it starts to go below the 45 inches. This will mean I shall have to trim some wood off the top of the supports for the frame work to allow the track through it. I will only need to do this for a distance of 8 feet (the distance from the top of the layout to the end of the second board down. In this distance using a 1:100 gradient the track will only drop 24ml. My supports are 70 ml in height meaning I still have 50 ml of timber support.

    Once the dropping track reaches the third board it is 76 Ml higher than the second board from the top. I shall probably need to cut 25 ml for the bottom of the frame work and supporting boards where the hidden track crosses them for some distance until it drops further. The large hidden loops on the left and right of the layouts are relatively new. I had not properly considered the clearance required to operate the huge turntables on the left and bottom of the layout. By inserting the loops I gain more distance to drop the track further while retaining my 1:100 gradient. I have described them a giant helixes. What I mean by this is that the loops are large enough to run a lower track below the one above. By dropping those threaded steel rods used to create a helix from the top of the layout I can thread ply supports through them and create as many levels as I want at whatever height I want depending on the length of the rods. It also leaves free the underneath of the layout for storage. All I need to do is cut as many duplicate pieces of ply as the number of levels I want to create.

    The length of the loop on the left is approx 5feet by 11 feet. This gives a distance of approx 32 feet in length. Using the 1:100 gradient this provides a distance between levels of approx 96 ml or nearly 4 inches. Certainly enough room for the single line to be spaced apart. On the right the loop is approx 8 feet by 19 feet given a distance to drop of approx 54 feet. In one loop the track can drop a maximum of approx 162mls. I am interested in opinions as to the desired clearance between the top of the turntable and the bottom of the base boards. As you can see it will be determined by the number of levels I incorporate into the loops (or giant helixes if you like to call them that). I thought that at least 12 inches or 300 mls would be preferable but perhaps 6 inches is sufficient.

    3. The two giant turntables are on the hidden plan on the lower left and bottom of the plan. You will note there are circles around then to show the diameter of turning them. They are not traversers. They will be mounted on wheels and will therefore be accessible from the ops area marked in grey. They will be manual and comprise two metal circular plates in the middle with a approx 6 inch diameter resting on each other. Candle grease should facilitate the rotation between the two. I have seen two of these on another layout and they work well (it is a OO Gauge layout). This will enable all of the rakes to be rotated through 180 degrees if required for the return journey.

    I have recently got access to a Summer 1960 passenger time table and been able to complete a Sunday passenger operation for this period, Listing every coach in every train rake. There are approx 45trains in the 24 hour period. Some 14 of the rakes are identical in terms of travelling up and down the line. This reduces my coach requirements to 31 rakes, including DMUs and suburban trains. I require something like 88 SK and 55 BSK plus a myriad of other coaches to simulate this level of traffic.

    The area at the bottom of the layout will hold the mountain to the west of Penmaenmawr. In recreating this feature I shall need to build the mountain to within 2 inches of my garage ceiling. The mainline runs around the base of this mountain going through a tunnel and appearing at the Pen-y-clip viaduct. I have this in the layout where the track is over the top of the sea area.

    I value all opinions re the distance between the baseboards and the turntables, so jump in and provide an opinion. Please feel free to ask any other questions as it may prompt me to reconsider an area I may have slipped up on due to my lack of experience.

    Thank you very much for your interest.

  23. Jon this is a pretty good idea and one I will consider. I want a bit of a rest from carpentry, but marking up the horizontal surfaces will give me that change, at least for a while. By then I might be ready to return to the wood working fray. I was going to start the laying track on the Conwy side of the Tubular bridge as I need to connect two pieces of flexitrack in the middle. This will provide a good point of reference for the track through Conwy.

     

    Today I spent the day moulding stone wall sections in preparation for the sea wall sections and the castle I need to construct. I have in the order of 11 types of stone wall in different finishes and scales. There are plenty of them.

     

    Comments are always welcome.
