A part-built 7 1/4 inch gauge locomotive, based on Roger Marsh's "Thomas II" design, reworked as a compact tender engine. This design has been popular with commercial miniature railway operators since the first one was built in 1979 (still running at the Beer Heights Light Railway), it is a powerful engine capable of pulling forty passengers all day long.

This engine has been professionally built thus far for a commercial railway. Due to an unexpected opportunity to buy another large engine, this project is now surplus to requirements.

Work completed to date:

Six wheel tender, 95% complete, assembled and running with roller-bearing axlesboxes, dummy leaf springs, coal bars and driver's seat. Requires brake gear and tank filler to complete
Main frames laser cut and assembled with buffer beams and foot well welded in.
Driving wheels turned from EN8, pressed onto 2 inch axles, quartering keyways cut, flycranks machined. All painted.
Axle boxes in cast iron with twin roller bearings in each
Wire-eroded expansion links in gauge plate with bronze die nuts
Complete cylinder assemblies ready to bolt on complete with pistons and Clupet rings, stainless steel ground rods, glands, valve chest and cover. Valve and buckle to be machined.
New steel boiler by Gerry Dowd, fusible plug, expanded-in steel tubes, complete with all paperwork, hydraulic test certificate and CE mark plate
Motion brackets cast in spheroidal iron, machined.
Ground stainless steel valve spindles, machined cast iron guides
Pair of crossheads machined.
Set of drawings

The work completed to date is to an excellent standard and would give a flying start to complete this large locomotive. The picture below gives an idea of the size of the finished engine.

Driving wheels diameter 9 1/2 inches
Cylinders 3 1/2 x 4 1/2
