643 203-3 is the trailing unit of RB 11565 (Herzogenrath-Stolberg), departing from the new station Aachen Schanz on 15 June 2004. This unit is one of those that were equipped with a first class compartment to operate in areas where trains with only second class are not accepted. I guess that the only things which seperate the first class from the second are the labels and maybe a door between them. The leading unit is 643 221-5, it has no first class.
