DRG locomotive types

The locomotive type (Gattungszeichen) of a German steam locomotive was a secondary classification system introduced after 1924 by the Deutsche Reichsbahn-Gesellschaft (DRG) and comprised four parts:

Example: A DRG Class 01 express train locomotive had the following type classification: S36.20. That meant: Express train locomotive (Schnellzuglokomotive) with 3 coupled axles, a total of 6 axles and an axle load of 20 tonnes

It was intended to use this type classification system for electric locomotives as well. But because electric locomotives could be used for any duty, this plan was given up.

The primary classification system was based on class numbers which, in the case of steam locomotives ran from 01-99 (see table, right hand column).
