Unsteamed in some years when it came to us, the boiler has had recent hydraulic and steam tests, with new certification issued. On the track it ran well, free-steaming and responsive to the regulator - there's some video of it on our YouTube channel here.
Boiler feed is by injector and axle pump - the mechanical pump well-sized for the job, keeping up with demand whilst not drowning the boiler. There is a second injector fitted with steam feed, although not piped up for delivery.
There is a driver's brake valve and vacuum gauge fitted, apparently the start of a project to fit vacuum brake equipment - it would require some pipework and an ejector to complete.
