Albtal-Verkehrs-Gesellschaft ('Alb Valley Transport Company', AVG) is a railway company owned by the city of Karlsruhe that operates rail and bus services in the Karlsruhe area, southwest Germany.

It also operates some of the region’s bus services and carries freight by road and rail.

VBK and DB Stadtbahn routes traverse AVG tracks.

[1] AVG dates back to the acquisition in 1958 of the Albtalbahn railway by the city of Karlsruhe.

It was this experience that led to the development of the Stadtbahn Karlsruhe and to the AVG operating over a much wider area.
