Regionalbahn

The Regionalbahn (abbreviated RB) is a type of regional train in Germany.Regionalbahn trains usually call at all stations on a given line, with the exception of RB trains within S-Bahn networks, these may only call at selected stations. They thusly rank below the Regional-Express train, which stops only at major stations on a route.

RB trains are subject to franchising by the federal states of Germany; whilst many RB trains are still operated by DB Regio, franchises often go to other companies, like Veolia Verkehr, eurobahn, Abellio Rail or metronom.

RB services make use of vastly different types of rolling stock; on electrified lines, double-deck cars or EMUs may be used, on non-electrified lines one will often find Class 218 locomotives with Silberling cars or newer DMUs like the Bombardier TALENT.

There is no obligation to use the term "Regionalbahn" for basic local services; some private rail operators therefore use their own names to denote their trains.
