DC electric 2735 heads D 424 (Cologne-Oostende) which is just about to depart from Aachen Hbf on 6 November 2001. On the platform some signals are visible. The three white lights form a Zp8 which says that the brakes are in order. The brakes have to be tested after a new loco was coupled to the train. Next to the Zp8, a circle of green lights forms a Zp9, which is the departure order. In front of the loco the double contact wire of the catenary is clearly visible.
