The SNCF Class A1AA1A 68000 is a class of diesel-electric locomotives of the SNCF. Originally a class of 80 locomotives, they were built for both passenger and freight service. They were ordered on 7 June 1961, the first entering service on 13 December 1963 at Chalindrey depot.[1] A further 5 were added by refitting members of the similar AGO powered Class A1AA1A 68500 with Sulzer engines, thought to be those formerly used in the BR Class 48 locomotives, D1702–1706.[2] Subsequently, 13 members of the class were rebuilt as Class A1AA1A 68500, 1 in 1963 and 12 in 1993. The last was withdrawn from traffic in 2005, with the exception of 68081 which has been preserved at the Cité du Train.[3]
