Having put up photos of 828 above, here is a rather different Scottish 0-6-0. An NBR ‘S’ class (= LNER J37):
This is another ‘new build’ clockwork engine, completed in 2009. The builder was the late Brian Caton. Brian built the loco for me as a friend in tandem with a live steam version for himself. I did pay Brian for the build, but nowhere near a commercial rate. Brian died, far too young, some years ago now, but folk may remember his incredible 009 live steam locos which appeared at several exhibitions.
The bodywork of no. 292 is tinplate. The strength and rigidity of the material has allowed very thin gauge plate to be used, thus 292 is extraordinarily light compared with the weight of a typical clockwork loco. No suitable driving wheels were available so Brian made a pattern and had castings made. As it happens, the wheel diameter, number of spokes and crank position are the same for 828’s driving wheels as for 292 — and 828 also has wheels cast from Brian’s pattern. The tender wheels on both locos are old castings, I think Bond’s.
Brian’s metal working skills were outstanding. No. 292 is beautifully and accurately built; I can’t fault it.
The large-diameter high-pitched boiler of 292 has allowed a large motor to be used. A post-WW2 Bassett-Lowke 4-coupled mechanism is fitted, back-to-front compared with usual B-L practice, thus driving the rear wheels. The generous headroom provided by the size and pitch of the boiler meant there was no need to tilt the motor. The overhang of the motor beyond the driven axle did have to be shortened to fit in the cab and this was done in conjunction with fitting a Teleguv in place of the original governor. The powerful motor in combination with a light weight locomotive has resulted in an exceptionally strong engine for its size. I have had 292 pulling five coaches on a garden line, admittedly on modern nickel silver track with very large radius curves. The Teleguv has also resulted in a long run per wind and almost silent running.
For the record, the motor was rebuilt with a Teleguv by Paul Mason, clock maker. Diane Carney made the works and number plates.
Brian Caton also painted 292. Correct transfers for the tender were not available and Brian used the best he could find. These were garish and the company initials and numbers were both too large. I lived with the oversized lettering for a couple of years but then took 292 to Ian Rathbone and he hand painted the tender numbers and initials in the correct style. Ian also added some more lining which Brian had decided was too challenging. Ian’s hand-painted letters and numbers are superb and a massive improvement on the previous transfers:
Note too the excellent finish produced by a thick coat of yacht varnish.
No. 292 is a superb loco and a great favourite.
The overall arrangement, a four-coupled motor driving the rear wheels, is the same in 292 and 828. In both cases, this has allowed daylight under the front part of the boiler. In both cases the motor projects into the cab. The NBR cab, with just a small side window, is of course much better at hiding the motor. The other advantage of the NBR design is the longer overhang behind the rear driving wheels which can accommodate the overhang of the motor.
As can be seen in the first photo, no. 292 has conventional cab control rods (i.e. rods with knobs on). The key hole on 292 is in a similar position to the key hole on 828, but without the benefit of a Westinghouse pump to disguise it. In line with Bassett-Lowke practice, 292 has no flanges on the middle driving wheels. Overall, 292 is thus a little more conventional than 828, but experience gained from 292 informed decisions during the building of 828. The Caledonian loco is inherently the more difficult design for a clockwork model, for several reasons. Less headroom for the drive spring (smaller diameter lower pitched boiler). An open cab making it hard to conceal if the motor projects into the cab. A very short overhang behind the rear driving wheels. The blue livery (any projection of the motor under the boiler in front of the firebox will be far less obvious in a black engine).
