John Fowler 4200019 / BR ED2-6

Industrial locomotives often had long service lives and, thanks to rebuilds, could end their careers quite different to how they started! John Fowler 4200019 was built in 1947 with a Fowler diesel and mechanical transmission for Batchelors Foods in Sheffield. In 1960 it was rebuilt by Thomas Hill with a Rolls Royce engine and hydraulic transmission [1]. The locomotive is now preserved at the Heritage Shunters Trust as BIGGA, after Batchelors Food's well known processed peas!

Five very similar locomotives (John Fowler 4200041-5) to this one were built for the LMS in 1947 though by the time they entered service it was for British Railways [2] as ED2-6. They worked for BR's Engineering Department until being withdrawn in the late 1960s [3].
