Hello there will be several large groups of enthusiasts in the Gt Yarmouth area doing the BLS tour on the 3rd of May, we will all be at a loose end on the Sunday morning, the railway has a diesel loco shown as working but would anyone know if its a ex BR loco or some industrial thing I've asked the question on face faceache just wondering if anyone knows on here, obviously if there is more than one loco out so much the better
