Unlike T 1000s, the T 2000s' control equipment was also modified so that a coupled set could be operated by a single engineer. One power car, number T 2057, has been preserved at the French National Railway Museum.

SNCF Class BB 20004 SNCF Class BB 20004 The SNCF class BB 20004 locomotive was a dual-voltage test-bed locomotive transformed from the damaged BB16540 in 1959. After the end of its test period in 1969 it was reinstated with its original equipment under its original number BB16540. SNCF had already experimented with three other dual-voltage locomotives in the 1950s, but these were all rebuilt from a DC locomotive and could only deliver their full power under 25 kV. Power output under 1.5 kV was reduced to 10% of the full power which is nearly negligible. This was however no real problem, as these locomotives
