The BB 16500 was the first locomotive from the “BB Alstom” family. Despite its output of only 2,580 kW, it was built in large numbers in order to get enough locomotives for the new 25.000 Volt power system. Like many of its successors, it had bogies with only one traction motor each and a two-speed gearbox for freight and passenger trains. With these, a top speed of 100 or 140 km/h is achieved with different tractive efforts. They were retired between 2002 and 2011.

Steve Morgan

The CC 40100 was a series of ten heavy four-system express locomotives built for the SNCF between 1964 and 1969. They were capable of all common AC and DC systems in Europe, but were mostly only used for service between Paris and Belgium. Externally they featured the “Nez cassé” by Paul Arzens. Six type 18 locomotives of the Belgian State Railways were virtually identical to the CC 40100.

Like other French locomotives, the three axles on each bogie were powered by a single traction motor with two gear ratios which could be switched while stationary. Here, these were actually double motors which were located in a common casing. Depending on the gear, they could haul 900 tonnes with 160 km/h (99 mph) or 200 tonnes with 240 km/h (149 mph). Their service ended in 1996 with the introduction of the TGV Thalys.

Joachim Lutz

The class BB 7200 locomotives are representatives of the generation with the distinctive nose shape with “Nez cassé”. They were the last pure DC locomotives in France and at the same time the first DC locomotives with automatic load control. They have bogies with only one traction motor each and were built with gear ratios for different speeds. In addition to the 160 km/h multi-purpose variant and the 100 km/h freight variant, three locomotives were built for 200 km/h. In 2015, the first were retired after being replaced by the Alstom Prima.

The WAM-1 was the first AC electric locomotive in India. It was developed and built by the European 50 Hz Group and its name stands for “Wide gauge, AC, Mixed service, first generation”. The French electric locomotives from this period served as models, although production was also carried out by Krauss-Maffei and Krupp.

In parallel with the WAM-1, Indian Railways also ordered the WAM-2 and WAM-3 from Japanese manufacturers. The WAM-1 was mainly used by the Eastern Railway in the Ganges plain. The use in passenger service ended with the introduction of the new three-phase locomotives in the 1990s. After that, they were only used in front of freight trains and in shunting duties. In the meantime, all of them have been retired, only No. 20202 “Jagjivan Ram” being preserved.

Between 1975 and 1977, the Yugoslav State Railways received a total of 39 six-axle electric locomotives for passenger and freight trains from Alsthom. They shared many similarities with the French CC 6500, but had lower power and a lower top speed. In the 363, too, only one traction motor was used in each bogie, the gear ratio of which could be switched between 75 and 125 km/h when stationary. They were nicknamed “Brižita” after the French actress Brigitte Bardot and later all came to Slovenia.
