The French word Autorail describes a single powered railcar capable of carrying passengers.
While the concept faded for a while, it has been introduced with a new range of vehicles for both standard and metre gauge lines.
Many autorails from the 1950s and 1960s form the basic transport of many French preserved railways, of Chemin de Fer Touristique (sometimes Historique).
The power of these machines allows them to pull a small number of trailers if passenger loads necessitate.
The raised centre section was attractive to tourists in scenic areas.
