A 5 inch gauge GWR 15xx built in the main to LBSCs Speedy design, but with modified valve gear as required to get the best out of the great mans design (OK then, to get anything out of it the original valve-gear was completely useless, not one of his best moments on the drawing board). As a result, this one runs well and notches up nicely.
Silver soldered superheated copper boiler, feed by axle
pump and injector. Cast iron cylinders with piston valves actuated by
Walschaerts gear with pole reverser in cab. Mechanical lubricator.
Originally built in 1993, it was overhauled by John Shawe
in 2002 when it was fitted with PTFE piston valve seals and new piston rings. It
runs well, paintwork is used but usable probably no worse than they looked
running around Paddington in the 1950s and the blowdown valve leaks
