In Germany, Luxembourg and Austria, the Regional-Express (RE, or in Austria: REX ) is a type of regional train. It is similar to a semi-fast train, with speed at about 70-90km/h as it calls at fewer stations than Regionalbahn or S-Bahn trains, but stops more often than InterCity services. The majority of Regional-Express services are currently operated by DB Regio, though a few operators have received franchise rights on select lines from the federal states. Several operators (for example Metronom between Bremen Hbf and Hamburg Hbf) currently operate trains that are similar to a Regional-Express service, but have decided to use their own names for the sake of brand awareness instead.
Regional-Express services are carried out with a variety of vehicles such as DMUs (of Class 612), EMUs (of Class 425 or 426) or, most commonly, electric or diesel locomotives with Silberling or double-deck cars, the latter often with new Class 146 engines. Many RE services run in hourly intervals, carrying line numbers and sometimes even names, varying from state to state.
