Early on in the history of the railways, the postal administrations used the railroad to transport mail. The rail mail cars were either placed individually in passenger trains or added in larger numbers as part of express freight and freight trains with mail transport. In the post-war period, the mail trains were shaped by the rolling stock of the former Deutsche Reichspost and were formed between large junction stations. Such mail trains consisted of wagons which, depending on their design, were used to transport letters or parcels. The letter mail was not only transported in the rail mail car but also sorted during the journey. Mail that had already been pre-sorted and was only distributed further at the destination station was transported in covered freight wagons - mostly rented from the DB, some of which were also owned by the Deutsche Bundespost.
