The BB 9400 was a French electric locomotive series for use on the direct current network of the Société nationale des chemins de fer français (SNCF) with 1.5 kV. The locomotives were built by EMC , Jeumont-Schneider and Fives-Lille in the years 1959 to 1964 in 135 copies.

history

Class BB 8400 locomotive with green paint

Up to now, locomotives for direct current with 1.5 kV voltage have essentially been developed by the SNCF and technical guidelines have been determined here.

Two years after the first BB 9200, the first locomotive of the BB 9400 series was put into service, which differed from the BB 9200 in particular in its drive with mono-motor bogies. In this form, a single-frame locomotive, the PO E 703 , was used in France even before the Second World War . Many of the locomotive's components are modular, with those of the SNCF BB 16500 for 25 kV 50 Hz alternating current and the two-system locomotive SNCF BB 25500 . Within the row there were two sub-assemblies with the arrangement of the pantographs:

  • BB 9401 – BB 9435 had single-arm pantographs placed on a frame ,
  • BB 9436 – BB 9535 had an arrangement of the single-arm pantographs on small blocks of the roof shape.

Originally the locomotives were equipped with a green box with numerous decorative strips made of aluminum based on the model of the BB 9200 . As these became dirty quickly, they were removed again in the 1970s. In the same time, the original curved corner windows were replaced by sheet metal. In 1981 the locomotives were painted with a brown roof and gray side walls (illustration), which goes back to a design by Paul Arzens . At the same time, the series 126 locomotives with the same drive concept for 3 kV direct current were purchased in Belgium .

For three decades, the locomotives were considered reliable machines for the medium-sized service. The BB 9531 – BB 9535 were equipped with speed-reversible transmissions, which is why they were also used in express train service . This design was derived from the two prototypes SNCF BB 30001 and 30002 . The majority of the locomotives, however, were used in freight train service, where they proved themselves better than locomotives with single-axle drives thanks to their more advantageous friction weight . In addition, they had a relatively low mass, which they preferred to use on routes with a lighter superstructure, such as after 1980 after the electrification from Bordeaux to Montauban .

As the mass and speed of freight trains increased more and more in the late 1980s, the use of the BB 9400 in this area declined. The freight trains were then taken over by the BB 8500 . The first retirement of the BB 9400 began in 1987. The delivery of the BB 26000 in particular made many locomotives superfluous. In the 1990s, the idea of ​​using the locomotives in light suburban traffic came up, which led to the conversion of 42 locomotives into the BB 9600 series by 1994. The locomotives that had not been converted were taken out of service by this time, and many vehicles have since been scrapped after the usable parts were used as spare parts for the BB 9600 push-pull locomotives that were still in operation . Two locomotives in the series have been preserved; The BB 9411 in Nîmes and the BB 9460 in Montpellier .

commitment

The BB 9531-9535 equipped with a manual transmission is known to have been used to cover the express train from Paris-Austerlitz - Orléans - Tours - Poitiers . The locomotives carried the train called Cyclops at a speed of 160 km / h. Other routes are known from Bordeaux to Montauban, Béziers - Neussargues , Ambérieux - Bellegarde , Ambérieux - Chambéry , Lyon - Avignon , Valencia - Miramas over the right bank of the Rhone , Lyon - St-Etienne and Bordeaux - Le Verdon .

The deployment depots include Avignon (since 1961), Paris S / W (1963–1965, one locomotive until 1973), Lyon (from 1966), Bordeaux (since 1981) and Tours Saint-Pierre (from 1990).
