The BB 17000 (also called Danseuses ) is a French series of electric locomotives that was built from 1965 to 1968. A total of 105 locomotives of this type were purchased from the Société nationale des chemins de fer français (SNCF). The locomotives have been decommissioned since 2007.
history
The locomotives belong to the large series of the "BB Alsthom". These were also called Danseuses because they tend to sway. A total of 105 locomotives of the type BB 17000 were manufactured up to 1968. There are also many sister locomotives that are very similar: 146 BB 8500 , 294 BB 16500 , 13 BB 20200 and 194 BB 25500 .
In the 1960s, the SNCF needed suitable locomotives for the new 25,000 V single-phase power system. That is why the BB 17000 series was commissioned and manufactured in two versions. A total of 105 copies had been built by 1968. They have been phased out since 2007; 50 were still in operation in 2015.
technical features
These locomotives are very similar to the SNCF BB 25500 except that they cannot run below 1.5 kV DC . The BB 17000 series was equipped with two gear ratios, which enabled freight train transport at 90 km / h and passenger train transport at 140 km / h. With a continuous output of 2940 kW, the locomotives were also suitable for being used on main lines in front of passenger trains. The locomotives are mainly used on 25 kV electrified routes in the north and east of France.
There are a total of three different car bodies. The 17001–17037 have a 13.604 meter long frame with a vertical front. The 17038–17105 have a 13.7 meter long frame with a vertical front. The 17005 is the only one with a small stem (nose) and a 14.38 meter long frame. This peculiarity earned this locomotive the nickname Donald Duck . She got this different box shape because she received a box with improved collision protection after an accident. At that time it was also given a different base that actually corresponds to that of the BB 25500 . Due to the modified car body, at 79 tons it is also one ton heavier than the other locomotives, which have a weight of 78 tons. The length over the buffers is also correspondingly different: 14.7 (17001–17037), 14.94 (17038–17105) and 15.57 (17005) meters. The dimensions of the bogie are the same everywhere. The pivot distance is 8.5 meters and the axles in the bogie are 1608 mm apart, which results in a total wheelbase of 9.108 meters. All wheels have a nominal diameter of 1100 mm. Each bogie has a single drive motor (monomotor bogie) that drives both axles via a gearbox. The type TAB 660 B1 motor is positively ventilated and has a rated current of 1050 amperes at 1500 volts.
The two single-arm pantographs of type AM 18 U are unevenly distributed on the 3.58 meter high roof. The center of the contact strip of the current collector on the side with the main switch is 4,271 mm apart from the center of the box, while on the other side the dimension is 4,239 mm. The middle joint of both pantographs faces the center of the box.
The locomotives have push-pull control and can run with another locomotive in double traction. For operation with passenger trains, the locomotive has an “equipment à Agent Seul”, which enables trains to be run without a train attendant. A voice connection is also built in between the locomotive and the train.
The locomotive has anti-skid protection and a multi-release pneumatic brake. At the front there is only one connection with shut-offs for the main air line of the compressed air brake and one main air tank line with 9 bar. For this, it has both a cable and a heating socket for the train busbar on each end . As usual in France, this is operated with 1500 volts and 50 Hertz.
In addition to the basic equipment, the locomotive also has the “ Contrôle de vitesse par balises ”, the “Repetition des signaux optique” and the “Radio sol train” installed as a train control system. The "Veille Automatique à contrôle de maintien d'appui" is built in as a safety driving circuit.
commitment
Most of the locomotives are used before trains on the Transilien Paris-Nord , Saint-Lazare and Paris-Est . But they are also used with Rame inox omnibus (RIO) on the TER Bretagne and in front of freight trains.
The first two discarded locomotives, BB 17099 and BB 17101, were sold to Romania .
The workshop responsible for these locomotives is the Technicentre Quatre-Mares (district of Sotteville lès Rouen ).
