  1. Fox bogies were widely used in the pre-grouping companies in the later 19th/early 20th century era. I have seen them in use on LSWR, LBSC, GE, GN, NER, HR, Caledonian, NB, ECJS and I suspect that the list is quite a lot longer. I haven't seen an increased depth on 4 wheeled bogies, but you may well be right if there was a perception that the loads were greater. The Caledonian 6 wheeled bogies do, for example, have deeper channels between the axleboxes, but the same depth as the 4 wheeled bogies for the sections at either end. All the 4 wheeled bogies that I have seen have clasp brakes on all wheels and the Caley 6 wheeled bogie (which I have drawn up as a future product if anyone is interested) has them on all wheels too. Not saying there isn't room for some that didn't though!!
  2. The bogies are available from me directly, as well as Justin's stand. I am taking the view that things should be post free at the moment too. https://miscellanymodels.com Actually I am away for a week (firmly in NER territory, if that makes it more acceptable! ) but they are in stock and I can send them as of next Monday.
  3. Hi all, Yes, these pipes are intended to be gas pipes. I do not have direct evidence of these pipe routes on NER coaches (although I do recall seeing some on the ends going onto the roof) but it is quite a common feature on coaches of the era. For example in one of my favourite pictures from HC Casserley and now owned by Ernie Brack.
  4. Fair enough on the smoke vents; as you say Dingwall is the exception! I wonder if it is because it had the little tanks for Strathpeffer? I will take a look at the paper, it does look good. Mark
  5. Looks smashing Jamie; it is so rare to see a proper size building modelled.
  6. Hi Richard, That does look pretty passable. Can I also ask as to the source of the stone paper you refer to? I can see its merits as stone takes a long time! A small point but the Highland (and I suspect many other companies) conceived their sheds so that the locos always pointed towards the front. This meant that they only needed to put the smoke stacks in a limited number of locations. Thus, both stacks should presume a loco pointing forward. Mark
  7. I think there are several processes in a sewage plant; one is an aeration of the material and it does have sort of whirlpools in it. However, I think this is a fairly early stage of the process and the material is less - urrmmm - clear! It will have rather more colour to it (do I need to say which one) and will have slightly more white froth in several locations in the bed where the air is pumped in. The later processes are to spill the now rather more clear liquid over filters. This is where you see the sprinklers slowly going around an almost black filter bed. Possibly worth doing a bit or research into the processes, as I am no expert its just my train used to go past them each day; Hersham I think they were! There is bound to be a British Standard on it somewhere! I enjoy your thread by the way. Mark
  8. Both! It was one of the first P4 models I built so I would have just been a teenager! Where does time go?
  9. Well done for the fish van; the Jidenco kits are not easy at all. This is what mine looks like. Missing the R by the look of it and I must do something about all the dust on the roof! Mind you, it will be 40 years old by now; agghhh where does time go?
  10. Jonathan, Go to High Peak Council's planning portal; which you can find here: https://www.highpeak.gov.uk/article/299/Planning-applications Most councils now upload planning applications that they receive, including the drawings. Thus, for many buildings there are drawings in the public realm that you can refer to. Given that Buxton station is listed and hence even relatively minor alterations require consent, there are a whole load of drawings of the building available through this. Older applications have not been uploaded, so look for applications post 2007 or so. Good luck, and I enjoy this thread. Good to see an LMS man!! Mark
  11. Do you have a "mint gauge"? Reference RSG in the Scalefour Society's stores. It is a very useful tool for finding misalignment through turnouts or tight to gauge sections.
  12. Nice to see the coaches developing. I find it imperative to solder a strip of square/rectangular section along the top of the etched sides. A piece 1*2mm or similar and make sure it is low enough not to foul the lip that is on the underside of the extruded roof but not interfere with the glazing. If you don't do this, the sides are always prone to being squished as the model is picked up and the sides picking up a bow as a result. Seeing your mention to the underframes; Palatine's underframes are well worth a look (and not widely known of). They don't have the chunky holes in them like the Comet ones and if you leave the flat portion of the Comet ones in place they make a convenient point to split the body from the underframe (much easier for handling and painting. Enjoy!
  13. Careful Mick, they have a very low rating and DCC will zapp them. You can see what happens to them here.
  14. Obviously, where there is water in a locomotive yard, there really ought to be coal too. The Highland, like many other railway companies of the time (certainly the Scottish ones), sought to stockpile coal. This was presumably insurance against coal strikes and allowed them to purchase coal at times when the price was favourable. Thus, quite substantial coal stacks where very much a feature of shed areas in the pre-grouping era. Typically, these were arranged in engineered stacks, with the sides formed in “dry-coal walling” and then loose coal behind. I can’t recall ever seeing this modelled, so I though I would change that! The actual structure of the loading bank was formed in plasticard and Wills random stone sheets, but with the mortar courses softened as I described for the water towers. The shape of the coal stack was formed with a piece of house insulation left over from a DIY job and then real coal used to form the effect of…..err……real coal. Actually, real coal does not look quite like real coal without a bit of effort. It does shatter into angular but irregular lumps like real coal (especially if lignite coal is used) but its glossiness does not scale down. However, a vigorous brush with generous amounts of soot black weathering powder takes the gloss back and the whole becomes quite convincing. You do feel as if you are going to get pretty filthy if you go up onto the bank – and until the whole is fixed with matt varnish, you would! Individual coal chunks were glued in place to form the wall structure. To get the effect, it is not enough to simply scatter the coal onto a bed of glue each chunk has to be laid individually with care taken to lock it into the course below – just like a real dry stone wall. Thus, the vertical walls of this took about a day to complete, scattered over about 8 stints because it is necessary to let the glue dry after every couple of courses to stop the layers collapsing. It is then possible to scatter the loose material behind the walls onto a layer of glue – the above picture shows the contrast in effects between the two methods. But it is hard work shovelling coal into tenders, especially as the locos got larger and their tenders higher. As befitting such an important place as Glenmutchkin, it has all the modern amenities for coaling engines, a hand crane and a large bucket! In this case, I have fitted servos to this so that it operates – partly as a bit of fun and also to slow things down in the yard to a more realistic pace without it getting too boring for the viewer. The crane operation was achieved by way of three servos – one to rotate it and then one each for the front and rear of the coal bucket. These are all mounted onto a cradle that is rotated by the former – thus as the crane rotates so too do all the servos and there is a quadrant shaped slot in the base to the rear of the post (just visible in the picture above) that allows the cables to rotate too without snagging. The base of the crane; the projecting rod telescopes into the actual crane (and there is a rod inside the crane post that telescopes into this too and appears below and onto which the servos clamp The cradle is mounted to a solid rod that is in turn secured to the actual crane. This then slides into the rod that can be seen projecting from the base in the picture above. This means that there is limited strain on the crane or the mount as I had feared it might otherwise snap with any heavy-handedness on my part (something I am prone to!). The rest of the crane was made with brass hollow section and pulley wheels from Bill Bedford. A series of guides were made of small section tube on the pulley wheels, at the winding drum and across the jib to retain the operating cables. The bucket was fashioned from metal sheet and is filled with low melt solder to give it as much weight as possible. It is secured to the servo arms with invisible thread – which is a nylon seamstresses material used for making invisible stitches. It comes in both clear (which really is invisible) and black, I used the latter. It is much better than cotton thread as that has a furry finish that looks terrible after a time or if it is painted. It is, however, very fine and rather wriggly to knot, so using it involves a certain amount of cussing! And this is what it looks like in operation………… A little of the bouncing about of the bucket is caused by it sitting on my servo test rig, so the act of changing the switches imparts a little vibration. Hopefully, when mounted on the layout this will be less obvious. I do still need to do the final detailing on this; tools, a bit of discarded debris and a couple of fellas from Modelu standing around doing nothing (because static people in animated poses look silly on a model layout!).
  15. Interesting you say blackening and then painting - do you chemically black the whole thing and then paint it?
