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 average speed at about 70–90 km/h (top speed often 160 km/h) as it calls at fewer stations than Regionalbahn or S-Bahn trains, but stops more often than InterCity services. The first Regional-Express services were operated by DB Regio, though since the liberalisation of the German rail market (Bahnreform) in he 1990s many operators have received franchise rights on lines from the federal states. Some private operators 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.

In Sweden, several regional trains reach 180 or 200 km/h. They are usually called just regional trains, or named after their respecitive regional transit administration. The most common train types are Øresundståg and Regina.
