Regional-Express (RE, or REX in Austria) is a type of regional train service found in Germany, Luxembourg, and Austria. It functions as a semi-fast train, making fewer stops than a Regionalbahn or S-Bahn but more than an Intercity or Intercity Express. RE services typically reach top speeds of 160 km/h, with some reaching 200 km/h on high-speed lines. While initially operated by DB Regio, many lines are now run by various private operators. These trains often use double-deck cars with electric or diesel locomotives.
