Hello everyone,

I'm starting this thread to log my progress in making some B&CDR locomotives and stock. Right now I have plans to make the 4-4-2 and the 0-4-2 tank engines :

 Image result for bcdr railwayImage result for bcdr railway

I'll be drawing these up in CAD and 3D printing them. I have a fictional Newtownards to Portaferry branch line in mind, so although I'd really like to make the 4-4-2 I think that I should make a nice train of bashed Hornby/Triang clerestories behind a little 0-4-2 to start with.

Thanks for reading!

A start on the 4-4-2...

It might not be 100% accurate but I'm liking it so far... One thing I've noticed is the Belpaire firebox should be a lot more rounded on the sides, something I will have to amend. 

 

A 14xx is arriving soon to donate a chassis to the B&CDR, I'll also take measurements from the outline of that to make the 0-4-2.

Brilliant stuff this 3d printing. Ive a long list of engines id like to try 3d printing it as does plenty of others I reckon! Number 90 has already been tried and succeded....BCDR tank will be wonderful to see too

So the 0-4-2 that I made this afternoon didn't quite go to plan:

image.png.f529e1b8fdd594d98078d4f1be582685.png

There's a lot wrong with it. The tanks aren't tall enough, the lip on the bunker is too big, the list goes on. I can't get the tank taller while keeping the lip and top details at the right height, if anyone knows how to do this in Fusion360 please do let me know! 

As it and the 14xx chassis that it fits are far too big to be the intended prototype I think it'll become a fictional class of locomotives for operating my fictional Newtownards to Portaferry branch.

 

When this line was built around 1898-1904 the CME realised that a class of modern tank locomotives needed to be built to operate passenger and goods trains along the line under the strict regulations of the Light Railways Act of 1896, and so a larger sister loco to the older 0-4-2Ts from Sharp, Stewart and Co found its way to the BCDR. Making the branch operate as a light railway was economical for the BCDR and apart from the construction of the locomotives there was no huge cost to opening the line. The locomotives had a light axle load, and the trains were usually relatively short.

Something like that, anyway...

I'm not entirely sure what you mean but I assume that something is changing when you don't want it to. My methods in Fusion are pretty brute force so you might know better than me but you could try the following;

Make a copy of the body that you are working on and turn this new body off. Do not move the body.

Extrude and remove everything away on the original body except the part you want to change.

Turn the original body off and the new body on. On the new body extrude/remove the part that you want to change.

Now when both bodies are turned on you should have individual parts, and you should be able to change the part you want to alter without messing with the other geometry. You can fix whatever inconsistencies remain afterwards and you can combine everything together when done.

Looks very nice! Good plan for the model too, as a ‘nevawazza’. What may help cement the illusion is incorporating typical BCDR features such as the smokebox handrail, quadruple front cab windows, and the curved tanks.

How's this? Handrail to go on later.

Thanks for this. What I mean is extruding the tanks upwards while also moving the details on them upwards too.

Instead of them staying where they are and the tank top moving around them (see above). If I go back in the history and change the height, the cab goes funny and holes appear...

I'll give your suggestion a go tomorrow.

An easier option in this situation might be to draw a rectangle on the top face of the tank and offset 0.1mm. Extrude this out the bottom of the body which will cut it in two, forming a second body. Use the move tool to move the top of the tank up and clean up afterwards.

I've started painting her, but not finished yet. Also, the 14xx I bought didn't come with traction tyres, hence the middle wheel sitting oddly. I will buy some of these at some point soon. I will probably print off a better body at some point too as the coal rails failed to print on this one and a few other minor things, but I'm happy enough with this so far.

Not much to report visually over the weekend. I've amended my design to include a bit more support on the coal rails and I've added valances. The traction tyres are now fitted and she runs much better, but needs a bit of weight over the trailing axle. I'll print of a 'Mk2' soon, get that painted up and ready to go. 

As for coaches/stock, would people recommend Ratio kits? I've found a brake 6 wheeler to 3d print from Thingiverse and I'll do that soon too, by itself it may form part of a track gang train or something.

I'm not particularly knowledgeable about the BCDR but from what I've read they used almost exclusively 6 wheeled carriages, plus they ran a goods service from Newtownards to Portaferry by road so plenty of wagons will be needed too! 

 

Thanks :)

Does anyone know which paint to use for the dark green livery? I'm thinking a Phoenix GNR loco green with BR mixed traffic lining transfers. 

Sorry, only seeing this now.

A very dark green indeed; don't use No. 30 in Cultra as an example, as it is totally incorrect. I would go a good few shades darker than BR loco green. Tried to find a pic just now but couldn't. If I do, I'll post it here. Someone else posted pics of BCDR loco green recently.

When dirty, like CIE grey, it could look almost black.

Lining was red and white.

Yes, they only had a few bogies, and most of these rarely strayed off the Bangor line!

To model the BCDR, six-wheelers are just not possible to do without, but there's good news here, as Hattons now have RTR 6-wheelers. Some of these are in maroon liveries. While these coaches are closest in design to GSWR designs, and in fact don't resemble other Irish companies at all, in the absence of anything else I'd get a dozen or so to make up a couple of BCDR passenger sets. Nothing buyable resembles BCDR bogies, but, again, a bit of artistic licence, and get a bogie with no end gangways to represent one of the several they got the NCC to build for them for the Bangor line. 

For the main part, you'll need 0.6.0 tender engines, or 2.4.2 / 4.4.2 tank engines.

BCDR coach livery: Black chassis, light grey roofs (weathered!), maroon ends and sides - same shade as LMS maroon, conveniently, as were the GSR, Clogher Valley and NCC! Post-war, many were unlined. Prewar all were lined pale yellow.

Wagons: Grey all over. The grey was significantly darker than the neighbouring GNR or NCC, almost like a charcoal grey. FITTED vehicles ONLY were often in a bauxite brown. Ironwork was body colour above platform level, black below, unlike GNR, GSR or other wagons which were body colour all over.

It is worth pointing out too, albeit going off on a bit of a tangent, that there seems to be confusion on when wagons were brown instead of grey.

Many British companies painted fitted wagons brown, others grey. The BCDR and UTA seem to have copied this, and in later days the GNR. The GSR and CIE never did - they painted everything grey, but about 1970 as a livery change, started painting all wagons brown. Nothing to do with being fitted otherwise.

The BCDR was unusual for Ireland in having several operators of private owner wagons along the way, in particular the open wagons of the East Downshire Co., based at Dundrum, and used for carrying coal. Provincial Wagons do a kit of these. The livery was plain grey, of a much lighter shade than BCDR grey, and with lettering in pale yellow instead of white. Ironwork was grey too.

There are no commercially available RTR wagons that approximate to BCDR goods vans of brake vans. Ordinary opens can be used, repainted in a very dark grey, to give a good impression.

@jhb171achill, thanks a lot for the information! I don't think I'll be able to afford, or indeed have the capacity for, such a large fleet of coaches, but one or two would be nice and the shared livery with the LMS is useful for finding paints. 

I note your point about locomotives, I found a few drawings in the Manchester science museum which I may use to make a nice tender engine.

Many thanks again!

You should be able to buy tins of LMS maroon from somewhere like Mark's Models or some such similar place. The new 6-wheeled coaches - maybe buy three or four to make one passenger set!

Look forward to seeing this develop. My dad’s introduction to railways was being set on the footplate of a BCDR loco at Donaghadee c 1948. He’s never forgotten the smell of coal and hot oil. Although my railway loyalties lie to the south and west of Ulster, the BCDR has grown on me over the years. I’ve come to appreciate the high points of its history such as the 1940s renaissance of 2-4-0 no 6, and the highly impressive Comber-Belfast timings. BTW Halford’s Rover crimson spray paint is a good and cheap way to get a nice BCDR carriage colour. Here it is on a little LSWR saloon I built a few years ago....

Thanks to everyone for the help. I haven't yet managed to print off my new body (sidetracked with 6th form and narrow gauge, so I thought I'd upload a picture of the CAD drawing:image.png.19f718287249ebb5b7d34d06d7666cc4.png

This is the 6-wheeled coach that I mentioned, not my design but I'm happy enough using it for now. I am thinking about the new pre-grouping coaches in NBR livery as they're quite attractive, however I would probably repaint them anyway to fit with any printed/kit coaches I paint.

I've printed the amended engine off and she's being painted, I'll share a picture in due course. 

As for a running space - my layout is a WIP end-to-end run set in southern England ca.1939/40. I have one station planned and half built but at the other end I am planning to have a halt which will double for the BCDR halt serving Portaferry. I will take Wootton (as preserved) on the Isle of Wight as inspiration for this:

2015-isle-of-wight-railway-wootton-station-2.jpg.6a25115712d2b1b3dedb9e657c760f93.jpg

A simple platform, headshunt and run round loop. The buildings will be painted in as passable colours as possible for both the SR and BCDR as from what I've seen they're relatively close, and I'll leave off any insignia or company names. I may have a level crossing over the headshunt for some visual interest. 

As for the name, I was thinking 'Portaferry Marlfield Road', 'Abbacy Road' or 'Portaferry Mountain Road'; I like the idea that the station is a short distance from the town itself. 

 

Any comments or advice on this are very welcome! 

Thanks for reading and stay safe :)

Sounds like a nice plan. Such a simple layout needs a rationale though, as in real life a terminus normally needs some kind of goods facility etc. Wingham (Canterbury Road) is about as basic as it gets, and it was atypical.http://www.disused-stations.org.uk/w/wingham_canterbury_road/

Are you going to pretend these facilities are offscene? Or perhaps this could be Portaferry Harbour, for passenger traffic only, a short extension from Portaferry proper.

I was considering having a small siding off the run-round loop (at the end furthest from the camera). At the IoWSR we are planning to make a goods feature there in due course and I believe the original station had some sidings there.

I like this idea a lot, but as I already have a town at one end on my layout and it's around 5m long (16ft) I don't really want to clog up the layout with buildings etc... I could always add the Illusion that the line continues on past the station as would have happened at Wootton in the steam days...

 

Thanks for the suggestions!

Yes, all that’s often required is a suggestion. A level crossing gate at the end of a line suggests continuity in a way that the normal buffer stop does not! This was my rather poor effort when I modelled 1930s Southern (based on Basingstoke/Alton Light Rlwy).
