In December 1962 locomotive No.50 received a boiler from one of the ex-NCC 2-6-0 tender locomotives, the boiler and firebox being overhauled and repaired at Derby.

In early 1966 and towards the end of their careers, the Class WT locomotives were involved in working notable traffic. This was on spoil trains that transported fill for motorway construction from the Blue Circle cement works at Magheramorne

The last of the Class WT locomotives were officially withdrawn in 1971 the last time one was in traffic being 22 October 1970. This made them the last steam locomotives in mainline operation in the British Isles

The RPSI is also looking at the possibility of building a new member of the class (No.58) to give them a second mainline tank locomotive considering the low availability of turntables on modern day lines.

Technical details

The locomotives were built with many LMS standard features such as a self-cleaning smokebox, rocking firegrate, self-emptying ashpan, side window cab and a simplified footplate together with others which followed NCC practice, such as a water top-feed on a parallel boiler (as opposed to the taper boilers being used by the LMS at the time), Dreadnought type vacuum brake gear, Detroit sight feed cylinder lubricator and a cast number plate.
