Built to a fairly pedestrian standard in the first place, the chassis runs on air in both directions after a fashion, although with wear evident in motionwork and valve gear. The valve chest gaskets leak and need replacement.
The commerically built CE-marked boiler by Devon Steam Boilers is in good condition - it's had a hydraulic test with new certification issued.
A new pressure gauge has been fitted; the injectors are fussy in operation and require either cleaning, re-piping or replacement.
The regulator is a ball valve with rod linkage from the cab - it requires a replacement gland to rectify a stripped thread.
