The locomotives were 16.2 m (53 ft 2 in) long, weighed 82 t (81 long tons; 90 short tons) and had a tractive effort of 260 kN (58,000 lbf) giving a maximum speed of 160 km/h (99 mph)[1]
Technically, the class was closely derived from BB 9200. They were fitted with one-legged type AM18B pantographs unlike the BB 9200s, which were fitted with diamond type G pantographs. Differences between the two classes were notable at the bogie level, in particular the suspension system. Only the last BB 9200s were equipped with rheostatic braking, while all BB 9300s were equipped with it. The louvres were longer than on the BB 9200. The driver’s cab benefited from new ergonomics and the standardised controls fitted to most locomotives built from 1965.
Operational use
BB 9322 hauling the Catalan Talgo at Genève-Cornavin, 1979
When first delivered, they were assigned to lines in the South-East region, to provide traction for the Rapid and Express trains. From 1967 to 1970, some locomotives were rostered to haul the prestigious TEE Mistral before the advent of the more powerful CC 6500. BB 9319 to 9331 were fitted with special hydrostatic compensated buffers between 1975 and 1981, necessary for hauling the Talgo III-RD trainsets of Renfe on the two services using this stock: TEECatalan-TalgoGeneva - Barcelona, from Geneva to Narbonne where diesel traction took over, during the period when this train was routed via Lyon-Brotteaux instead of Grenoble; and the Barcelona-Talgo sleeper train, linking Paris and Barcelona, from Paris-Austerlitz to Toulouse, where it was again handed over to diesel traction.
In 1977, the arrival of the new BB 7200s at the Villeneuve depot for service on the Paris-Lyon-Marseille artery displaced the less powerful BB 9300s. They were then progressively transferred to the Toulouse depot. By 1981, the entire class was allocated to Toulouse to operate express and mainline trains between Paris and Toulouse or Bordeaux, and on the cross-country lines of the South-West, as well as a few freight or postal trains.
At the end of the 2000s, the BB 9300s, like their BB 9200 cousins, experienced a sharp drop in activity due to the appearance of new regional multiple units.[2] Some were stored out of use, the others remained in operation on the Teoz connections, then CIC and TER services, still around Toulouse and Bordeaux. They were regularly used to move empty coaching stock between Bordeaux and Juvisy.
Depot allocations
The Villeneuve depot received all 40 locomotives of the class as soon as they were delivered, from 1967 to 1969. From 1977, they were gradually transferred to the Toulouse depot. By 1981 they were all at Toulouse and would remain so until the end of their career.[3]
Fleet list
The last members of the class were withdrawn on 2 September 2014[4]
