Royal Bavarian State Railroad (K.Bay.Sts.B.) class 3/6. With digital high-efficiency propulsion. Headlights digitally controlled. 3 axles powered through side rods. 2 traction tires. Electronic reverse unit. Length over buffers 24.9 cm (9-13/16").
Connoisseurs have termed the S 3/6 as one of the most successful and beautiful locomotives in the world. The unusual tapered cab, the cone-shaped smokebox door and the immense cylinder block were characteristic features of this popular class. Its efficient coal consumption and good running qualities proved its use in regular operation. The two inboard high pressure cylinders and the two outboard low pressure cylinders were coupled to the center driving wheels. A very high level of thermodynamic efficiency was achieved with this four cylinder propulsion system. The last of the locomotives of this successful class was not retired until 1960.
