A new, unsteamed Great Western 0-4-2T to Martin Evans
Dart design, built to an excellent standard by a retired professional
engineer, the man responsible for the nicest
3 inch gauge Britannia Ive ever had in a particularly strong
runner - along with a beautifully-finished Class
37 diesel and a very fine 3
inch gauge Hall.
Professionally-built silver soldered copper boiler by
Bishop-Richardson, initial hydraulic test at 275 psi for a maximum125 psi
working pressure. Stainless steel radiant superheaters, feed by twin injectors
fitted beneath the footplate with overflows piped out to and cleated beneath the
steps, with auxiliary hand pump in the bunker.
Stainless ball-valve regulator same as we use in
Stafford and the only way to go for a completely reliable,
smooth-operating, leak-free system which can be replaced with an off-the-shelf
component should the need ever arise.
Blowdown valves are fitted with separate heads on stainless
shanks, as per full-sized valves, which avoids the working faces being ground
into each other as the valve closes.
The grate removal of which has never been one of
Evans strong points is mounted with a pin through the inner firebox sheet
extending beyond the foundation ring, making removal and replacement easy.
Water tanks are dummies given the amount of cutouts
inside for reach rod and top-feed plumbing, there is minimal capacity at the
best of times, the engine has been set up to draw water from a driving
Cast iron cylinders with slide valves actuated by
Stephensons gear with screw reverser in the cab. Sight feed lubricator with
oil tank beneath cab floor.
Axle boxes have an oil reservoir machined into the top, with
galleries feeding oil to the journals and hornblocks they are filled with an
oil gun via the hollow axles, which is an excellent system, I had a 57xx
similarly equipped some years ago.
The first 7 inch gauge locomotive since my Stirling Single made it into the library which has passed muster with Mrs P and been allowed into the house, where it currently brings a little bit of Swindon to our hallway. For those preferring something a bit more nationalised, I've got 1454 in as well at the moment in British Railways livery - it will be listed as soon as I can find an afternoon spare to give it a run.
