The SNCF BB 8100 was a French class of 1500 V DC electric locomotives, used on the Paris-Lyon "Imperial" rail line.

[1] A post war development of the BB 300 class, they were much loved by the SNCF, 171 locomotives were built between 1948 and 1955.

Expansion of the 1500 V DC electrification in the 1980s allowed the locomotives to roam further than their original Paris-Lyon line.

[2] They were also exported to other countries, including the Netherlands where they were designated class 1100.

[3] The locomotives can be seen in action in the 1950s along the Paris-Lyon line in a promotional SNCF film "De Fils en Aiguilles".
