RegioExpress

RegioExpress, commonly abbreviated to RE, is a category of fast regional train service in Switzerland, run by Swiss Federal Railways (SBB CFF FFS) or other railway companies (such as TILO, BLS, tpf, THURBO or RhB, previously also by transN).

A few lines also serve stations in Germany, France and Italy.

Swiss Federal Railways describes the trains as ones that serve "rapidly into the regions".

One of the main lines which ran as a RegioExpress line (abbreviation: RX) was the Rheintal Express, from St. Gallen through Sargans to Chur (the other was the CityVogel from Zürich to Konstanz).

As of the 2004 timetable overhaul, the RegioExpress was introduced as faster Regio (formerly regional) trains; the term was thrown into expanded usage.
