The SNCF BB 26000 locomotives are a class of dual voltage, four axle B'B' electric locomotives capable of a top speed of 200 km/h built by GEC Alsthom between 1988 and 1998 for SNCF. The locomotives are also commonly known as the Sybics. The class were built to fulfil both freight and passenger roles; the specifications included the ability to haul 16 Corail coaches at 200 km/h (120 mph) on a 0.25% gradient, and to haul a 2,050 t (2,020 long tons; 2,260 short tons) freight train at 80 km/h (50 mph) on a 0.88% gradient. The locomotives are a two cabin design with the body built out of steel, two pantographs are fitted; one for 1500 V operation, the other for 25 kV operation. A 25 kV AC supply is stepped down and rectified to 1500 V, a 1500 V supply feeds the power electronics directly. Each of the three elements of the thyristor bridge based three phase inverter circuits are connected in parallel, with the two three phase supplies per motor being series connected. For speeds below 15 km/h (9.3 mph) one supply voltage reducing chopper circuit (French:hacheur) per motor bogie is used to assist control. The power electronics of the two motor bogies are connected in parallel, and are
