The upgraded line Cologne-Düren (ABS 4) seen from the access to the temporary station of Sindorf on 8 December 2001 looking east towards Horrem. On the right side is the old line. The first ballast layer for the highspeed tracks is finished, the rails for the northern track were put down at a wide gauge. After aligning, a gantry crane will ride on the rails, bringing the sleepers. On the left is a temporary platform.
