7¼"

'Samstipur' ran for a while on a private railway on the Isle of Man. After being loaned to Beer Heights, the rarrangement was made permanent. Rebuilt as 'Jools' in 2018 and officially named by Jools Holland OBE. One very unusual part of the rebuilt was a dual-control driver system, making the locomotive  uniquely suited to driver training and 'driver experience' courses. As well as a second steam regulator on the back of the bunker, the locomotive has a camera observing the gauge glass, paired with a video screen in the van behind.

Built for the Wills Garden Railway in East Sussex, owned by the late Bob Wills
