Two Einheitshilfsgerätewagen (what an awful german word, let's just say these cars contain equipment that is needed in case of derailments and other incidents) standing in a siding in Aachen Hbf on 26 July 2001. The one in front has still the older yellow livery, while the one behind has a new red painting. A warning sign hangs on the coupler because the cars are connected to a stationary electricity supply. The inscription on the gangway footplate says "Shunt with care".
