Téoz

Téoz (formerly Corail Téoz) was a brand name used by France's national railway company, the SNCF, to denote long-distance reservation-obligatory passenger rail services on certain SNCF routes. The SNCF established the Téoz system in 2003 as an attempt to bring certain key routes up to the same standards as TGVs where high-speed lines are not available, leaving ordinary Corail trains to serve the rest of the non high-speed intercity and interregional network. It was merged into the Intercités brand in 2012.
