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
