DB 140 078 passes through Köln West with a short freight that is led by two tank wagons with sulphuric acid (these are recognised by the rack works on top of the wagons). When these sulphuric acid trains pass through Köln west, no other trains from the other direction are allowed to cross due to safety regulations. Köln West, 24 July 2002.
