The A class trains were the first trains used on the Berlin U-Bahn network. These trains were used for 88 years in Berlin from 1901 to 1989, and besides the smaller profile trains, it also went to the bigger profile trains when there are not enough trains on the network, such as the case of U5, U6 and U8.
