Nicely proportioned, if massive, tank that switched or handled freight traffic over relatively short distances. Its stability came from placing the tanks 450 mm (17.7") lower than earlier designs The running gear included a rigid wheelbase of only 3.75 m (12 ft 3 5/8 in). The first and sixth axles were given considerable side play within a Golsdorf axle arrangement while both the leading and trailing axles were Adams radial types. Nine-inch (229 mm) piston valves supplied steam to the cylinders. Doug Self, in [
