Class (BR) 03

The Class 03 engines were built between 1930 and 1938 as express train locomotives for routes that were only suitable for axle loads of up to 18 tonnes. 298 examples of this engine, whose construction was based on the Class 01, were built by the firms of Borsig, Krupp, Henschel, and Schwartzkopff. Its reduced weight was achieved by the use of a light sectional frame, smaller boiler and smaller cylinders. From engine number 03 123 onwards the pumps were located in the centre of the locomotive and from number 03 163 the locos had larger leading wheels.
