Here is the classic 1.5KV DC cavalry of the Paris Charolais Depot in 1974. All these engines are waiting assignment on passenger trains starting from Paris Lyon station. From the left to the right you can see: 2D2 9125, CC 7122, an unidentified BB 9300, BB 9241, BB 9430, 2D2 9112. The most modern is the 9300. The powerful and then recent CC 6500 are missing from the picture, because they are on the right, outside of the picture, in the roundhouse. Today, the depot is gone (have a look at Google Map or Earth).
