It’s actually more than likely there was an overlap Alan. Lovely work. I do like black Irish tank engines ;) 

Yes, me too🙂  It's a shame one of this pair didn't make it to Witham Street.

After a very enjoyable weekend with Patrick Davey's Brookhall Mill at the Bangor Show last weekend, my loco-building gene started to agitate again. What next? A number of folk have suggested (and keep suggesting!) a BCDR Baltic but those things still have too many wheels and whirly bits. 

As well as all things BCDR, I have an abiding affection for scruffy little shunters, both steam and diesel and in my to-do drawer for a while now has lurked an etched kit for a Hawthorn Leslie 0-4-0 saddle tank crying out to be built. So I've made a start on it.

Since it's not by any stretch an Irish loco, you'll find the build in the 'British Outline Modelling' part of the forum.

Get you re valve gear Alan. Thank goodness the SLNC never bothered with such twentieth century monstrosities. What about No6 or 16 next? Know what you mean about that gene too- I am planning out a 10thou footplate right now…,

Vintage Irish Railways - Northern Ireland - BCDRIntroduced as a Beyer Peacock built class in 1924 this is Belfast and County Down Railway 'Large' Atlantic tank No. 16 on the turntable at Queen's Quay mpd.This is a Bob O'Sullivan negative and my thanks go to Robert Gardiner for the location. [Mike Morant collection] Vintage Irish Railways - Northern Ireland - BCDR. The clarity in this pre-war shot of Belfast and County Down Railway No. 6 is a wonder to behold. This Beyer Peacock one-off loco dated from 1894 and lasted in service until 1951 but then languished in store for a further five years which makes one wonder if there might have been efforts to preserve it.Some locomotive history from Joe Cassells: This very long-lived engine worked the 11.45 Newcastle  train on Saturday 15th January 1950 - the day before the line closed. The late Mac Arnold, an expert in these matters, reckoned that she never steamed after this although she survived under cover for so long that there was a feeling she might have been preserved. [Ted Pettman / Mike Morant collection]

 

😆 Yes David! By coincidence I’ve been pondering No6 for a while. That particular wheel arrangement, along with 4-4-0s too seems to be tricky to get working properly so I’m tempted by the challenge. I have a copy of Mike Sharman’s little book ‘Flexichas’ in which he describes a novel approach. I’d like to try it! 

A bogie tank would be good too. I did one from an Adams Radial but it would be nice to get a bit closer to the prototype with a scratch build. 


What are you planning with that footplate?

Sounds good Alan. No 6 in either incarnation would be delightful. As for me, I am returning to a long-stalled project to build an ex-GNRI 4-4-0, a J class….now on its second attempt at a chassis…..bottom pic shows attempt 1, before I managed to find a Beyer Peacock GA. Top pic shows bogie almost ready to roll.

Alphagraphix do the County Down 2-4-0 in 7mm scale and the MGWR G2 as well. The photo on the website of the latter is the one I built. Did a GER E4 2-4-0 as well, back in the day. Nowhere near as challenging as a 4-4-0, because they are not much different to an 0-6-0. Bit of side play and springing on the front wheels and Robert is your father's brother!

 Well, mostly...

 A bit more progress with Number 29. Some nice wheels from Alan Gibson...

Then, some paint on the frames, gearbox in, wheels on and quartered using my trusty G.W. Models wheel press and quartering jig. A great little device that takes some of the agony out of a tricky job. Wouldn't be without it now.

Rods held on temporarily with bits of wire insulation. We have a chassis that rolls under finger power without any tight spots. That's a relief!

Motor in and under power, it shuffles along very nicely.

Now, about that bogie....

Still travelling hopefully,

That wheel press looks the business 💪

After the distractions of industrial railways, both standard and narrow gauge, it’s back to the County Down. After much pondering, I’m going to have a go at one of the BCDR’s 2-4-2T tank locomotives.

IMG_9681.thumb.jpeg.ff4138cbff67bc9b74be6e49d02a1e9b.jpeg

Beyer Peacock supplied two of these in 1896 and 4 more in 1897. Before long they were edged out by the more common and more successful 4-4-2T bogie tanks. The first one was scrapped in 1924 but some were still working in 1949.

Deciding how best to build a 2-4-2 chassis, I rummaged through my collection of guru advice. In Mike Sharman’s little booklet “Flexichas”, there is an elegant design with a floating gearbox cradle and compensated pony trucks each end. Elegant but complicated. I closed the book and tiptoed quietly away.

Iain Rice’s “Locomotive Kit Chassis Construction” has a photo (page 48) of a 2-4-2 chassis with radial trucks at each end. That might be do-able and it might steer better than simple axles with sideways movement at each end.

So here we go. As usual, I started with the rods. I used an Alan Gibson universal rods etch (4M92) and a little jig made from PCB and brass rod to make sure both rods were the same length. (If they’re not, game over)

I’m going to try these radial truck etches from London Road Models.

Received wisdom suggests that the chassis needs to be narrowed at each end to allow the trucks to do their thing. This usually means joggling the frames. On a kit with nice half-etched lines for folding, maybe. On a scratch build and in my hands, I could see disaster looming with the likelihood of chassis frames bent in all sorts of unhelpful directions.

My solution is frames made up in 3 flat parts with the end sections overlapping and fastened inside the centre section. Even this was difficult enough to build straight. More jigs.

OO chassis spacers for the centre section and narrower 10mm ones for the end sections.

For the coupled wheels, one fixed axle and one with hornblocks. Poppy Woodtech chassis jig pulling its weight again.

Remains to be seen if I can make this work. But nice to be back on the County Down 😄

Seriously clever stuff - got to love those jigs! My Alphagraphix 2-4-2T uses a similar system to the one for Cleminson 6w coaches with the pony wheels lightly sprung to both guide into curves and stay on the track.

 Mostly successful, but remains a bit of a problem child because the pony wheels can stick, while in a ideal world it would be nice to have them with pick ups to spread that load as well.

 Hence will be watching with even more interest than usual.

 Looks a super project and having just bought some universal rods from Gibson, that little jig is a very timely reminder!

And we're off!  Have you decided on a livery and number yet Alan?

Probably one of the longer lived ones Patrick - No 7 which apparently came to grief in an accident at Queen's Quay in 1949 or No 27 which was scrapped around 1951.

Livery options include:

a) Vauxhall Burgundy Red, because I've got the paint

b) GNR(I) unlined black, so it can sneak in undetected at Brookhall Mill

c) Some variation of BCDR lined green

Probably c) 😄
