No. 4

S.M.R. No.4 started it's life at the Dudley Zoo railway. No.4 is a Petrol Mechanical Bo-Bo, based on a GWR 'Flying Banana' railcar. She was built in 1946 by G & S Light Engineering as a GWR outline 4w-4wPM with a 20hp Morris 6 cylinder engine and fluid flywheel mechanical transmission. She carried no name or number when first built. At Dudley Zoo she was altered to a 4-4wPM c1946. By August 1957 she had moved to Sutton Park, where she became No.4. Here a torque converter was added to the fluid flywheel, making her a 4-4wPH, however a date for this addition is unknown. She went into store with the rest of the Sutton Collection at Oldbury c1962 and moved to Cleethorpes in January 2002 . She still has her original engine.
