There are several well known examples of Colletts’ ‘14xx’ class tanks to be seen on our smaller preservation lines due to their light weight making them very useful. There visual proportions also make them instantly recognisable as a lovely little branch line loco. Designed in 1932 they were numbered as 4800-4874 and were all built with auto train control for use with autotrailers on push-pull services. A later batch in 1933 were numbered 5800-5819 but were not ATC fitted. During 1946 the 48xx batch was renumbered to 1400-1478 leaving the 48xx numbers free for oil burning locos of the 28xx 2-8-0’s. The 58xx series were unchanged.
During BR ownership, a large top feed casing appeared on some in front of the splendid dome. Footsteps and handrail over the rear cab roof on the fireman side only were also added and of course the smokebox number plate instead of the painted number on the bufferbeam.
From experience gained with our previous beginners models, we have simplified the construction even further. The electric kit contains all that you need to build a nicely detailed model and will include a motor/ gearbox unit and wheels. Space and suggestions are provided for battery powered control systems, but the wheels will need insulating for two rail operation.
The steam powered kit contains everything required to produce a simple, working, live steam model able to run for about 15 minutes on a boiler of water. It will include the handpump, which will allow the model to be kept in steam for as long as you like. The axlepump will be produced as an optional extra enabling the loco to pump it’s own water to maintain boiler water level on longer uninterrupted runs. It is commonly fitted to larger locos but is still being proved for this model.
GAUGE ONE STARTER KITS
These are ideal for those whose machining facilities or skills are limited or whose modelling time is at a premium. They are a good stepping stone from the 4mm and 7mm kits into the world of gauge one live steam, before tackling one of our more advanced designs.
The loco kit is assembled using nuts and bolts and glue with no soldering required. This will be done by ourselves where needed. The boilers are built, tested and certified in house. The steam chests and cylinder units come part assembled with pistons and valves in place ready for you to carry out the final assembly and seal them up. Laser cut steel frames, rods etc will need a little cleaning up and some piloted holes opening out to size with a drill. The etched brass components are supplied as flat sheets with only the simplest of bends left for you to do. Where these bends are required there is a fold line etched half way into the brass, allowing a neat, sharp bend. The boiler wrapper, the cab roof and the footplate droppers will be formed by us. All essential pipework will be formed with the fittings soldered in place. The wheels will be on axles and quartered. Detail castings are in brass, nicklesilver or if only cosmetic, whitemetal.
All machining is done. Pressure gauge, screws ,nuts, rivets, ‘O’ ring seals, springs etc. are included to complete the assembly. You will require some hand tools such as some fine files, small screwdrivers and spanners. Small pliers and tweezers are essential to position screws and nut where fingers cannot go. A drilling facility (which could be an electric drill on a stand) may be useful.
The model making hobby is littered with part built projects which have been abandoned because the modeller has hit a problem. We offer a ‘Get out of trouble service. It could be advice on the phone, a practical soldering training session in our works, correcting a mishap or setting valve timing. We include two hours free support or training session in our works and will try to advise over the phone during normal working hours. Over and above the two free hours there will be a nominal charge.
