BR Standard Class 5MT 4-6-0 73156 was the trivial load for BR Sulzer Type 4 1Co-Co1 diesel electric D123 LEICESTERSHIRE AND DERBYSHIRE YEOMANRY. The pair descended slowly past Woodthorpe with 73156 making hideous noises as air was compressed in the cylinders. I hope that the people from Bolton, that own 73156, know about this abuse. It really is no way to treat a locomotive.
