The rapid-transit railway Rhine Main had the first completely traffic-red vehicle park of the German course AG. This status was maintained until the end of 2003, when the S-Bahn Stuttgart handed over the orange-white and orange-pebble-gray units to Frankfurt. After just over a year, the S-Bahn were completely painted red by the z-position of the last orange-pebble-gray unit 420 376 early 2005. Until 2005, there was also the last pebble gray orange 420 (apart from 420 001) in Frankfurt, but this train was scrapped in the spring of 2005 in Trier-Ehrang.
