SNCF Class BB 17000

The SNCF Class BB 17000 B-B was a class of AC electric locomotives built between 1965 and 1968. The class was used for suburban duties on railway lines around Paris,[1] notably powering VB2N push-pull sets. They were monophase locomotives (running off 25 kV AC overhead supply) and had the nickname "danseuses" or "dancers". By 2020 the 105-strong class of locomotives had all been withdrawn.[2]
