80150 - British Railways Standard Class 4MT Tank Engine

Status Awaiting Restoration


The latest addition to the Mid Hants Railway fleet, newly acquired from Glamorgan Council in a deal that was struck in return for our ex Bricklayers Arms turntable, which they intend to install at Barry as part of their plan to turn it into a mainline destination.

80150 was allocated to Guildford Shed during some of its service life, so perfect for our railway. It was sold to Woodham Brothers of Barry in January 1966. Possibly the last of the class to be saved from Barry, it was purchased by the Wales Railway Centre of Cardiff in 1988. It was moved back to Barry in 1993 following cosmetic work for storage where it remained in the former Bus Depot. As a result, it is in reasonable condition considering how long it has been since she was withdrawn from service.

Any help and offers regarding acquiring the missing bits would be greatly appreciated! Please contact us through RAILMAIL, we'd love to hear from you.

80150 moved from Barry to the Mid Hants, arriving at Alresford on the afternoon of the 19th January 2011. Work on the fabrication of common parts has already started by the team working on Standard 4 75079.
