The CargoSprinter is a freight multiple unit designed to transport freight or equipment. The CargoSprinter was designed by Windhoff GmbH (Germany) in the mid-1990s. Initially seven vehicles were built for Deutsche Bahn. Four were built by Windhoff and had the reporting code DB class 690. Another three closely similar units were built by Waggonfabrik Talbot ('Talbot Talion') and given the reporting code DB class 691. The design did not lead to further freight work, several of the trains were later converted for other uses including tunnel rescue trains.
