A Schnellzug is an express train in German-speaking countries, where it refers to trains that do not stop at all stations along a line. In Germany and Austria it is also referred to colloquially as a D-Zug, a short form of Durchgangszug ("through train"), and express train services were often given numbers preceded by the letter "D". The similar term, "snälltåg", was used in Sweden until January 1980.
