The SNCF Class BB 17000 B-B AC electric locomotives built between 1965 and 1968. It performs suburban duties on railway lines around Paris,[1] notably VB2N carriages. They are monophase locomotives (running off 25 kV AC overhead supply) and have the nickname "danseuses" or "dancers". By 2020 the 105-strong class of locomotives have all been withdrawn.[2]
