SNCF - This unidentified BB 12000 is seen in April 1982 passing Hornaing, heading Somain from Valenciennes. The power plant (stopped in 2013)  of Hornaing can be seen in the background.

At this time, freight trains and "crocodiles" engines were very frequent on this line.

This image is taken with an Instamatic Kodak, with very limited speed and light managing capacities.
