    Bit by bit I am getting on with with the backscene. I think I have set myself a difficult task, trying to get a feel of depth and perspective in 2d. If I was a skilled artist it might be easier just to paint it, but I am not so the only thing I can do is the collage of photos method.

    I have played around with the panorama tools in Affinity. They work well with stitching a set of nice countryside photos together but can’t really cope with the complexity of a row of slightly different tenements. Perspective is also an odd thing, getting a feeling of depth is a case of using shadow, but it tends to work best if you are looking at the picture from a narrow angle not a wide one.

    So here are a couple of snapshots of the progress to date. It is just sitting there for now, there are a few joins that need touching in. Not sure about the chimneys, they look ok front on but not at an angle. That said it is a backscene, hopefully the focus of attention should be on the foreground.
     




     
     
     


    Halfway, lets see how the other half works out.

    So I have been making some bay windows. A few false starts but I think the ones I have ended up with have come out all right. Looking at the way the platform building was constructed; it is essentially a set of regularly spaced lateral girders holding up the roof supported by brick pillars. Th bits in between can be thought of as curtain walls , and the most symmetrical bits are the bay windows, hence the reason for starting with them is that defines the areas in between.

    Anyway , first thing some fancy windows. As ever the silhouette helps, effectively scribing all the astricals. I then ran some dilute ink into them and some paint round the edges.



    The inner and outer frames are added on the flat. helps to pre -paint them.



    So there we are just cut them out and stick them together. The dado is made up from 1mm quarter round with a strip of 1.3 mm 10 thou stuck on top.



    The walls were brick, but the L&D tiled them. In the case of Partick central brown below the dado, white above. They were laid in the same pattern as plain bond brick, but were smaller. The bit shown is experimental, not happy with it yet.
     


    Oh, and I made some chimneys based on photos of the originals. Really, simple plain ones? Heh , I wish……



    Slow but useful progress.

    A bit of stock construction, always a joy to do . In this case a pair of CR Dia. 11A CCTS from the latest “True lines Models “ kit. Historical notes can be found in “ Caledonian Railway Wagons” by Mike Williams, many thanks to Tony Brenchley of the CRA for producing the kit.

    Ok, so preamble over, lets have a look at it all. A cast resin body, etches for the chassis and springs and castings in brass and whitemetal for details.



    The body tends to curve inwards at the top, seems resin does this. So first step make a roof that is stiff enough to correct this. A simple structure designed and cut of the silhouette forms a roof support that is strong enough to correct the body curve and support the roof itself.



    Roof in place, its a tight enough fit to just clip in. Body has some holes drilled and the droplight filed out. Oddly these vehicles seem to have had one glass and one wood droplight.



    On to the chassis . This is sprung using a system similar to thet of the Bill Bedford chassis. It goes together accurately. These wre dual braked , so a fair bit of stuff hangs off them.


     


     

    Basic painting and with wheels in, it runs freely and the springs do spring. I’ll be interested to see how well it runs on the layout in practice.



    Ok, body next.

    Drummond built two of these small 0-4-2 tanks in 1885 for working the Killin branch. The design ran well and formed the basis for the Caley pug. Superseded by 0-4-4 tanks in 1895 they travelled the CR network before settling at Dawsholm shed where they worked the North Clyde industrial lines and the odd passenger working. So my period and location. Last one withdrawn 1947.
     

     
     
    I made the model mid 1990s I think. Some of the body is the old Jidenco etch made originally for Anchoridge which ended up with Falcon. I bought it in an incomplete state, so much was scratchbuilt, particularly the chassis. Basically I made an 0-4-0 with the rear axle driven and the front pivoting, the trailing wheels were a sort of bogie. That led to crosshead clearance issues and a tendency for it wander badly, the couplings were always off centre. No idea about the origins of the open frame motor and gears, they never meshed well and it was always noisy. It sat for many years until recently when I decided to give it a run.
     
    Hmm, time for a rebuild.
     
    New chassis made up, correct pattern Gibson wheels. I chose to drive the lead axle with a mashima like motor and a HL gearbox. The centre and trailing axle have a simple beam compensation. Took me two tries, the lhs sandbox was above the footplate. The cylinders are still to be stripped and repainted.
     
     
     

     
     
     
     
    Hmm . I had a look at the body. Not happy. A session in the brake fluid and a lot of bits fell off. So a body to rebuild as well.
     
     
  5. Dave John
    The body needed a fair amount of sorting out, a lot of bits fell off when it was being stripped. It isn’t the best paint job, but painting is not my favourite activity. As ever with the CR a lot of awkward brightwork but I have tried to tone it down a little to give a practical in use look. I also simplified the lining a bit.
     
     
     

     
     
     

     
     
    The main reason for the rebuild was to improve running. So a bit of video showing 263 on a trip working. It now seems to run fairly smoothly.
     
     
     
     
     
     
     
    The lining for that was from my last sheet of Modelmasters LNER / CR lining and it seems to be out of stock everywhere. The issues with Modelmaster have been discussed elsewhere on rmweb, so I don’t want to go into them here. Suffice to say it seems I’ll have to find an alternative source with sufficient radii to fit CR locos.

    These are made from the latest True Line Models resin body produced by the CRA. Many thanks to all involved.
     
    The description pre-diagram means that they were built bfeore the introduction of the official diagram book and therefore don’t have a diagram number. More details here;
     
    https://www.crassoc.org.uk/forum/viewtopic.php?f=17&t=1479
     
    I have built them in my usual way, copperclad sub chassis, rocking W irons, internal sprung buffers, all the bits from 51L.
     
    Resin bodied wagons are very light, so the large crate and the load under the sheet are weighted.
     
    Anyway a couple of pics. slightly faded livery, getting on a bit by the Edwardian era.

    Anyway, good luck everyone.

    Dead easy, several suppliers make plastic ones. Buy some and plant them ?
     
    Well, no. These are not any old telegraph poles, these are the telegraph poles of the Caledonian railway. As with so many aspects of pre-grouping different railways did things in a different manner. “Signalling the Caledonian” by Jim Summers has an entire chapter on the subject giving many details and a couple of useful pictures of the L+D under construction so combined with photos from elsewhere I know what I’m trying to build.
     
    So, for my location and period big A frame poles where possible, though single poles if space is limited. Alternate long / short crossarms with two insulators. The original shackle type insulators were replaced very early on, so Cordeaux style insulators on J hangers.
     
    Stripwood and dowel from Cornwall model boats, insulators from Express models. I had a play about on the bench. Hmm. It didn’t take long to realise that in order to make a consistent set of parts and assemble the posts in an accurate manner the first part of the exercise would be to manufacture a set of jigs.
     
    This is what I have come up with. This photo shows the three crossarm jigs, a bit of square brass tube with holes in and a catch as an end stop in two sizes.  Wood in, drill holes, lift catch, slide out.  The lower one has the catch tube in two parts forming a place to bend the J hangers. The one on the left is to hold the crossarm while superglueing the J hangers in.
     
     

     
     
     
    A photo of an assembly jig laminated up from bits cut on the silhouette.
     
     

     
    That’s the method, should keep me busy for a bit.

    Making all the poles and fitting sockets for them has kept me going for a few weeks. Chilly weather and bad light slow it all down a bit.
     
    The poles are 3mm dia dowel sanded to about 2 mm dia at the top. I doubt I could drill a 3mm hole through the baseboard square enough to make the poles stand upright so I made some sockets from spare brass tube, 25 mm long with bits of wire soldered on. The bit across the bottom acts a stop but still lets any debris fall through.
     
     
     
     

     
    That lets me use a bit of greased dowel to set the socket upright, once happy its sitting square some glue can be dribbled down the sides to secure it. When set a bit of ground cover round it and the pole looks like its embedded, but can easily be removed if needs be.
     
     

    A photo of the poles ready for a coat of primer. You may well laugh at the finial on the one that will go by the station building. Well, I did say these are not any old telegraph poles, these are the telegraph poles of the Caledonian railway. The Caley did put finials on telegraph poles that were in obvious public view.
     
     

     
     
    Painting them all next.
  9. Dave John
    Some photos of the poles planted in their sockets. I managed to get the spacing fairly even at 60 - 65 yards, the preferred Caley distance.   The camera is much harsher about verticals than the eye, particularly along the length of the layout. People used to Glasgow might be familiar with the effect, tenements do tend to lean back a bit. The time to panic is when they start leaning forwards.
     
     
     

     
     
     

     
     

     
     
     

     
     
     
     
     
    I’m happy with the overall effect, I think the effort to make them Caledonian rather than generic ones was worth the effort.

    Another year passes. At a first glance it might seem progress at Kelvinbank has been slow, a few wagons made and an old loco refurbished. However from the perspective of me enjoying the layout the major step forward has been the building of a lever frame and sorting out the signalling system. So some pictures on that theme.
     
    1 class No. 2 heads east towards Kelvinbank. The home is off if a correct route is set out of the storage yard and the section switches are set properly. The distant is cleared if the signal protecting the crossover at Kelvinbank is off.
     
     

     
     
    The platform home, No.6 is on as the preceding train is still occupying the next section.
     
     

     
     
    A condensing jumbo, No. 283 is held by the signal at Kelvinbank. Looking at photos the condensing pipes were kept well polished.
     

     
     
    The preceding train has now cleared. ( Actually just correctly stabled in the west sidings) So lever No. 6 can be pulled off. Using the duster of course.
     

     
     
    No. 283 can then proceed westwards.
     
     

     
     
    The signal under the bridge is an odd one. The real Partick Central had a signal at the east end of the platform about 20 yards the other side of the bridge. I can’t put one there so I made a Stevens and Sons tunnel signal which the Caley used elsewhere on the underground lines. 29 class No. 203  is held there, The signal is controlled from the lever frame but will not clear until the traverser is properly set and locked.
     
     

     
     
    No. 263 heads west with a short goods. The distant is cleared only when the signal into the west storage sidings is clear. Archibald McGregor hopes it is going to be clear all the way .
     
     

     
     
     
    Building and installing the lever frame has increased my enjoyment of operating the layout considerably. It is something I have been swithering about for a long time, but all the available solutions were either too small and fiddly or too large and would be visually overpowering in that location. Of course none were  cheap. I think the decision to scratchbuild was the right one, the frame just feels to be the right size and the action is smooth and positive.
     
     
    My compliments of the season to everyone, I hope you get some solid modelmaking time.

    Another year passes.
     
    I was running some trains and in my head as the carriages drew level with the platform I heard the guard shout,
     
    “ This is, er is ….. Um,  well dunno where we are really, but we have arrived……….”
     
    Yep, I have never got round to making any running in boards, so I though I had better address that pronto.
     
     
    There we go, now we know where we are.

    Time for spring cleaning so I have given the railway room a good  going over this week. Dust accumulates and I’d rather be making stuff but if I don’t keep on top of it I will have twice as much to do as all the stock fills up with fluff. Not to mention all the points, signal and things that just seem to jam up if you don’t.
     
    However essential cleaning is it cannot be described as photographically interesting.
     
    This is a LNWR D 466 open carriage truck made from the 51L etched brass kit. Would it have run on CR metals ? Possibly, taking a carriage  to the shooting estates of the rich perhaps. Who knows what is under that sheet.
     
    So here it is, tidied up and fitted with magnetic ajs.

    So its a model railway site, why blog about research? Well, research is half the fun of building a model and while doing it you find out about all sorts of interesting things. Even if you don’t end up building the model it is still an important part of the hobby as a whole.

    Anyway, I mentioned last week that I fancied building the elevated section across the window based on the L&D at Bowling Harbour. Research starts with maps, drawings, photos and descriptions. But if possible nothing beats actually going to see, measure and photograph the real thing. So myself and the Caledonian pup sallied forth to have a closer look.

    So, a bit of a general view. The swing bridge is under the big white cover, currently undergoing repairs and restoration. The whole section of the line is now a walkway / cycleroute, part of the route all the way along the north clyde, and well worth a day out.




     

    The viaduct was built in the early 1890s, so a first guess would be that it be built in the local red sandstone. A closer look shows that it is a mass concrete structure, with powdered sandstone used as a colouring. An excellent set of guides to historic buildings in Scotland is available at;

    https://www.historicenvironment.scot/archives-and-research/publications/?audience=7&publication_type=41&q=Short+guide

    Many are interesting in their own right, but the salient point is that Bowling Harbour viaduct would have been one of the earliest mass concrete railway works.

    So a closer look, thats 3 colours of concrete.



    A view of the underside of an arch, the “day joint” can be seen where water has seeped through.



    From the end, shows the concrete parapet. Just a selection of the 60 + pictures I took.



    So all I have to do now is build a model of it. Well based on it.

    All in all a good day out, goes to show that railway modelling is more than just sitting in the house making things.

    Ever had one of those projects which just take on a life all of it's own? You know, the kind of project which you just start thinking how about a bit of a mockup might be? You then squint at it and decide to carve up some foam board and tack that in place to see how it looks. Next thing you know some new styrene sheet has arrived in the post, oh well let's just put a bit of that on to see how it feels.

    Weeks go by and you realise that the concrete monstrosity has taken on a life of its own. Really it's about time to put those two boards back in the layout and run a few trains. Get the room cleaned up, hoover up offcuts off the floor and the Caledonian pup.

    So here it is in place. A few photographs with a trains running over it. Still a lot of work to do, but thats the basic structure formed. Painting it all is a whole other story, however that can wait a bit, I fancy a bit of wagon building for a rest.

    I’m still unsure about a backscene, thats it just neutral against the blinds. Though I did get round to cleaning the windows.












     


    So Concrete Bob, how about a job?

    Well there we are, No. 203 in service. It looks all right from a distance, but harsh close ups show my lining inabilities. I did try some of the 2 part Fox transfers where you overlay black on a red/white line, but I just couldn’t get them to look right. The CR red/black/white was subtle with fine lines, hopefully one day a transfer maker will take pity on us.
     
     

     
     
     
     

     
     
     
     
     
     
    Then again what matters is how it runs. These engines were built for trip and shunting work, so a bit of video showing 203 doing just that.
     
     
     
     
    I’m quite pleased with that. It will never win races with a 90-1 reduction, but it has considerable tractive effort and is very smooth, all previous pickup problems eliminated. The acid test is pushing a full train backwards through pointwork buffer to buffer and it passes that easily.
     
     
     
  16. Dave John
    Many years ago I made a CR 782 class from the SE finecast kit. There are some pictures of in in service in some earlier blog posts. The basic whitemetal body was fine, pretty accurate and it went together well. It was getting to look very tired, needed a repaint and some details were the worse for knocks and being stuck back badly.
     
    I was never entirely happy with the chassis. Centre axle drive, semi rigid with slightly rocking outer axles. Never picked up really well, too highly geared and the motor filled the cab. Hmm.
     
    However the most obvious fault is that it is the wrong loco.
     
    A bit of history. The 9 members of the 29 class date from 1895 and were fitted with condensing apparatus for working the Glasgow central lines. The same basic design was used for the later 120 members of the 782 class built between 1898 and 1913. So for where I’m based the 29 class is a bit more appropriate.
     
    Right, it was 782 class No. 245 and now its going to be 29 class No. 203.
     
    Chassis built up. AGW frames and wheels re used. Rear axle driven from a high level gearbox and extender with a mitsumi motor. Compensated with high level hornblocks which I thought were a very clever fold up design. Having a silhouette makes cutting balance weights a doddle.
     

     

     
     
    The body ready for quite a lot of filling and a spot of primer. Backdating to a 29 class mainly involves extra pipework, a westinghouse pump, air tanks and different footsteps.
     
     

     
    Paint shop next.
  17. Dave John
    The painting and lining seems to have gone fairly smoothly with this one. I used the same double transfer technique developed for the Grampian Corridor stock which helps. Certainly not as sharp as an expert painter could achieve, but I know my limitations.
     
    I have painted the interior in a simple fashion and added a guard and some parcels, mail bags and a tandem. Very little of that can be seen , but it gives the impression of use.
     
    Anyway, a couple of posed pictures.

    General
    I have been relaxing a bit, doing some layout maintenance and just running trains. All is now running smoothly and I can sit back and watch…..
     
    Well that was the idea. One of the problems with having a real good clean up of the railway room is that you end up with a nice clear workbench. All the tools put away tidily, the materials stocked in the right drawers. Yes, well. They say nature abhors a vacuum. I think we should change that to plasticard abhors an empty workbench.
     
    So a read of the wagon book, a look at some diagrams. Diagram 21 Loco Coal wagons. All easy shapes to cut on the silhouette, stick them together. Add a few bits of wire and brass and I end up with a couple of wagons.
     
    A pic of them in the raw state ready for a spot of primer.
     

     
     
    Compared to a photo.
     
     
     

     
     
    In the last blog Mikkel noticed the old dumb buffered pig iron wagon sitting there as the GCS passed. It is a funny wee thing, pre diagram and based on a photo. It is a bit of a pet wagon, probably the first scratchbuilt EM wagon I made way back about 1990. It really does look like wood, because it is made of wood with brass bits stuck on. The bolt heads are just spots of epoxy. Rather crude perhaps, but I’m rather fond of it.
     

  19. Dave John
    Progress on the 670 is delayed at the moment until I get the parts for the gearbox. Can’t be helped, difficult times slow things down.
     
    Anyway, I need to build something. I had a browse through drawings and books and settled on a D27 Machinery wagon. ( the CRA does sets of wagon drawings on a cd ) 
     
    So with a bit of luck here is one I can make from the stuff I have.  The body is laminated from 10 thou styrene cut on the silhouette. Bit of an odd wagon, big plates on the sides riveted  to an internal frame of angle sections with a planked floor.
    Nice and simple.
     

     
     
     

     
    As you know I like to be able to drop wheelsets out, makes it all easier to paint too. Personally I think it also makes wagon building easier. All that faffing about getting it perfectly square and making sure all the wheels sit on a perfectly flat surface so they touch the perfectly flat track?  Not something I ever managed to do very well.
     
    Anyway all that really means is just a pair of low profile internal compensation units soldered to a bit of coppeclad. Lands for ajs if I decide to fit them.
     

     
     
    Some lashing points made up from bits of scrap etch.
     

     
     
    Some primer, then the invasion of the rivets…..
  20. Dave John
    Well, there we are, a slap of paint makes all the difference.
     
    Rivets are Archers, easy to apply and they make a big difference on a model like this. No idea what is under that sheet, but it is heavy so this wagon moves as if it does have 16 tons on top. The chains and shackles were fiddly, but add to it all I think.
     

     
     

     
     
     
    Catching a bit of evening light.
     
     
     

     
    You can see that this wagon is properly scotched. There is a good reason for this, D27s like the other wagons in the same style, had no handbrake. Run as specials they would have wagons with handbrakes either side. Given that loaded it might be 27 tons that sounds a bit dangerous though I doubt they ever travelled outside the industrial areas served by the Caley and probably only in special short workings rather than as part of longer trains.
     
     
    So just for fun and I think typical of how it might have run here it is passing through Kelvinbank. Archibald McGregor hanging on and hoping it isn’t going far.
     
     
     
     
     
     
     
    I now have parts for the Cl.670 gearbox, so it is hopefully going to progress a bit with that.

    I seem to be in a wagon building mood these days. Dunno whether I’m locked down, locked up or or which tier of the cake I’m on, so wagon building is a cheap and time consuming activity.
     
    Now it might be argued that I’m getting my ratios wrong again, too many unusual wagons and not enough of the bread and butter diagrams. I’d agree, but the fun is in the odd stuff. I therefore decided to have a shot at one of the 1896 built D38 glass well wagons. Decent pics in the wagon books and a diagram for the basic dimensions.
     
     
    The wagon was built on a steel channel frame. Plastic channel has too thick a web to my eye so I soldered this up with brass channel sections from Eileens Emporium. The 19’4” wb makes it a long and awkward thing so I made a jig up on a bit of scrap wood. The W irons on this wagon were straight edged with no knee so I cut them from 0.3 mm brass sheet.
     

     
     
    The floor and well are from 10 thou styrene, cut on the silhouette and laminated. The bottom edge isn't as grubby as that, odd how the pic came out.
     

     
     
     
    The well itself is a tight fit between the wheels, the original being 3’ 11 1/2 “ wide. EM back to back is 16.5 mm, so it just fits.
     
     

     
     
    I think I’ll keep the frame and the body as two assemblies as long as possible. Difficult to paint if I jump the gun and glue the two together, but that gives an idea of how it will look.
     

     
     
    Sides next. 
     
     
     
     
  22. Dave John

    General
    The main assemblies for the wagon are now largely complete.
     
    Frame has been detailed, spring castings should have more leaves but those look ok to my eye.
     

     
    Body has the sides fitted. and the floor is planked. Note the holes in the body sides. I think these were to enable the screw clamps to be tightened up when used at a lower level, together with a pair of clamps at the bottom of the well.
     

     
    The fiddly bit was making the support frames. This has taken me three attempts to get the proportions right and find a method for glueing all the bits together. I will cut away the part between the bottoms of the uprights after painting, for now its useful for strength and ease of handling.
     
     

     
     
    A photo of it all sat together. It looks the part, but I wish I had some better idea of the design of the interior parts. However I suspect that such info has now long vanished.
     
     

     
     
     
    A coat of primer and bolthead detailing next.

    The D38 glass well wagon has given me a challenge but I’m reasonably happy with the overall result.
     
    The support frame has a slight lean, but it is only really noticeable in closeup and square on photos. As specials I think the wagon would be in good condition for the Edwardian era, it is in its first decade in service. I therefore just gave it some very light weathering.
     
    If someone has any transfers a scale 1” high that say “OIL” then I’ll buy some. those 3 dots above the axleboxes will have to do for now.
     
     
     
     

     
     

     
     
     
     
     

     
     
     
    I don’t usually go in for helicopter shots, but this shows the interior detail and the size of the well in context. The screw jacks holding the crate are peco trackpins, which I have found over the years to be very useful for everything apart from pinning track down.  I have improvised the tie down rings, I assume something like that was fitted.
     
     
     
     
     
     
     

     
    Those interested in Caley wagons will note the mysterious mark on the rh end of the solebar. Clearly seen on the original so I aded one. We might find out what it means one day.

    There we are, the D63 in service after its 30 year refurbishment.

    I’m not sure that I’m completely happy with it but perhaps we are all getting a bit harsh on ourselves since close up photography shows up all sorts of things that are just invisible from normal viewing distances. You never know, one of the rtr manufacturers might bring out a very nice version. Probably by the time this one has been in service for another 30 years……
     

    So a close up pic;



    Aye, well. In practice these vans would have spent most of their time on coal traffic so thats the service I will be using it for.

    Back at the bench again. The Caledonian built 40 Dia 25 lime wagons from 1886 to 1888. They were essentially a Dia 22 mineral wagon with a roof.
     
     
    The CRA do a drawing of it, which gives the wb as 8’6’’.  I don’t think that is correct. The Dia 25 is essentially a Dia 22 mineral wagon with a roof, and they are definitely a 7’9” wb. The Diagram book gives the Dia 25 wb as  7’9” as well.
     
    So I scanned in pics of both types of wagon, scaled them to size and superimposed them. Axleboxes and solebars lined up, so I’m going with  7’9” for the Dia 25.
     
    That sorted, out with the silhouette and some styrene chopping.
     
     
    A couple of pics of progress to date.
     
     

     
     
     
     

     
     
     
     
     
     
     
     
    Next I think I will give it a coat of primer then some archers rivets.
