Another jump into the archives. In November 1999, TUC RAIL finished work on re-building the Hammerbrücke, located on the classic railway line connecting Liège and Aachen. On November 5th, stabilizing runs were organised on the second track, right before entry into service. For these runs, a certain amount of tonnage had to pass over the newly laid tracks. This can be done with loaded ballast cars, but for the occasion 3 recently stored class 18 locomotives enclosed between 2 class 55 diesel engines were used. Summing up to 30 axles and 785 tons.

The special combo started in Welkenraedt and made trips over the new track at increasing speeds. The train even went as far as Aachen-Süd.
