Dual-current version of SNCF's CC 6500 locomotives, this small series of 4 locomotives registered CC 21001 to CC 21004 are assigned to the Dijon-Perrigny depot to be used mainly on the Paris-Dijon-Vallorbe axis to tow fast and express trains including the Trans-Europ-Express “Cisalpin”. Like the CC 6500 locomotives, they receive the "Grand Confort" livery based on red and gray underlined by an orange strip.

The CC 21003 delivered to the SNCF in 1974, took part in 1977 in a test campaign in the United States of America under the registration X 996 AMTRAK with the specific DC equipment removed. After testing and returning to France, she was returned to type. Faced with competition from the three-current TGV trainsets in Paris-Lausanne and Bern, the 4 CC 21000 locomotives had their equipment dedicated to 25 kV alternating current definitively removed between 1995 and 1996. They were then renumbered CC 6575 to CC 6578 on this occasion. These 4 locomotives were canceled between 2005 and 2007.

The CC 6500 "Maurienne"

Intended to be used for less noble services on the Culoz-Chambéry-Modane line, the CC 6500 "Maurienne" (CC 6539 to 6559) delivered in 1971-1972, receive a green livery and are fitted with friction switches for power supply by 3rd rail.

From 1977, their 3rd rail equipment was gradually dismantled and they were used interchangeably with the other “red” CC 6500s on the South-East network. Some “Maurienne” locomotives were repainted in “Grand Comfort” livery in the mid-1980s.

The CC 6549, 6558 and 6559 from the Vénissieux depot, will be among the last machines withdrawn from service in July 2007.

SNCF's first CC 6500s

The CC 6500s are the latest 1.5 kV machines designed without power electronics. They are suitable for towing passenger trains at 200 km / h and freight trains at 100 km / h.

They take the original shape of the “broken noses” created by Paul Arzens for the CC 40100, with inclined windshields.

They receive a so-called "Grand Confort" livery based on red and metal gray underlined by an orange band, except for the 21 "Maurienne" locomotives (CC 6539 to 6559) in green livery and fitted with rubbers for the 3rd rail . From 1970, these locomotives, with a power of 5,900 kW, were used for the prestigious "Capitole", "Aquitaine" and "Mistral" trains until the entry into service of the TGV Sud-Est and TGV Atlantique trains. After this prosperous period, followed a decline towards freight train services and regional TER trains before being reformed between 2003 and 2007.
