Bachmann Branchline OO 31-627B Class 3F 3520 LMS Black Deeley Tender. A detailed model of the Midland Railway 3F class 0-6-0 goods engine. These useful class 3 engines were capable of hauling light passenger and goods trains, ideal for local pick-up goods train service. Developed from older and less powerful engines these locomotives lasted well into the British Railways era. Enthusiasts know them best from the Somerset and Dorset line, featuring in Sir John Betjemans' film of the line to Burnham-on-Sea. The Bachmann model if powered by a motor hidden inside the boiler and firebox, with a diecast chassis providing adequate weight for realistic trains to be hauled.
