54 was the last member of a class of four locomotives (numbered 51 to 54) constructed at the Leeds factory of Kitson and Company Ltd, which was absorbed by Robert Stephenson and Hawthorn early in the Second World War.
It spent all its working life at Stewarts and Lloyds at Corby, hauling iron ore wagons, until its withdrawal in 1969 when it was purchased by two members of the Museum’s Bishops Stortford branch. It arrived at Chappel in 1973, following which it was fitted with vacuum brakes and steam heating equipment in order that it could work passenger trains. It was named ‘Penn Green’ during 1974 after the shed complex where it was based.
1987 saw it purchased by the Museum from its original owners. After many years of use as the main locomotive on service trains, 54 was withdrawn early in 1992 for major restoration work, including the construction of a new firebox. This being completed, the locomotive returned to traffic in early 1993 in a new Blackberry Red livery.
The locomotive was taken out of traffic in late December 1994 for rectification of defects in the new firebox. Contractual problems ensued, which were resolved in late December 2000. Work to being 54 back into use recommenced in 2007, and following a major overhaul, which resulted in a new side tank being constructed and the locomotive being rebuilt as a licensed Thomas the Tank Engine replica.
