25235, BR Class 25

Built at BR Darlington Locomotive Works and delivered new as D7585 to Toton on 13 February 1964. Derby and Darlington were building different parts of the class at the same time, which is why some Darlington engines carry higher numbers than Derby ones delivered later.

Location and status last confirmed Bo'ness & Kinneil Railway, August 2026. Subject to verification.

Carried both D7585 and 25235; the two are one locomotive.
