7 1/4 inch gauge "Holmside" 0-6-0ST

A 7 1/4 inch gauge National Coal Board 0-6-0ST to Martin Evans' "Holmside" design, a large, powerful tank locomotive for this gauge.

This one has come to us from the builder, complete with a driving truck containing a water tank which feeds the pair of injectors.

The commercially built boiler has had recent hydraulic and steam tests, with new certification issued. The engine runs, with some wear apparent in the valve gear and motionwork. Drain cocks are of the automatic type - they're certainly automatic opening, but more reluctant to close.

Injectors both work beautifully between 30 and 100psi, hand pump is effective, the safety valves are reliable with no accumulation.

Saddle tank has a slight leak from one balance pipe boss, however only the hand pump is fed from the tank, the injectors pick up from the water tank in the driving truck. We'd be tempted to ditch the hand pump and fill the saddle tank with ballast for adhesision.

An engine that can be run "as is" (and there's some video of it running up and down our portable track here), with scope for improvement over winter.
