This is where the branch line from Horrem to Kerpen crossed the mainline Cologne-Aachen. The bridge was removed long ago, but the pillars remained. Some years ago, when the upgrading project at the mainline began, the northern pillar and a part of the line next to it were removed to build two new tracks. Looking from the southern pillar on 1 February 2002, the new tracks and the recultivated remains of the old line behind them are visible, the old tracks next to the pillar are hard to see.
