The BB 16500 (also known as Danseuses ) is a French electric locomotive series that was built from 1958 to 1964. A total of 294 locomotives of this type were purchased from the Société nationale des chemins de fer français (SNCF).
history
These machines became necessary in the late 1950s and early 1960s in order to have enough suitable electric locomotives for electrification with the 25,000 V single-phase power system in the north and east of France.
This locomotive series is the first of the large series of the "BB Alsthom". They were also called danseuses (dancers) because they tend to waver. With an output of 2,580 kW, they are weaker than the following series with 2,940 kW and they also differ in the car body from the successors, for example the typical "hump" on the roof between the pantographs is missing. However, there is no difference in the construction of the chassis and the bogies. Related to it are the 46 BB 8500 , 105 BB 17000 , 13 BB 20200 and 194 BB 25500 .
technical features
The BB 8500 series is equipped with a gearbox with two gear ratios that can be switched at standstill. This makes it possible to increase tractive effort at the expense of speed. In the freight train position , 90 km / h (today approved for 100 km / h) and in the passenger train position 140 km / h.
The car body is 13.618 meters long and the length over the buffers is 14.4 meters. The pivot spacing is 8.5 meters and the axles in the bogie are 1,608 mm apart, which results in a total wheelbase of 9.108 meters. All wheels have a nominal diameter of 1,100 mm. Each bogie has a single drive motor (monomotor bogie) that drives both axles via a gearbox. The motors are of the type TAO 646 A1. Both motors are force-ventilated and have a rated current of 1,250 amps at 1,100 volts.
While the first locomotives had mercury vapor rectifiers , the last locomotives were delivered with silicon rectifiers .
The two single- arm pantographs of type AM 11 are symmetrically distributed on the 3.584 meter high car roof. The contact strips of the two pantographs are 8.4 meters apart. The middle joint of both pantographs faces the middle of the box.
Conversions
The number 16540 was converted to the prototype BB 20004 in 1959. This was used to test the dual-flow equipment. It is the direct predecessor of the BB 20200 and BB 25500. It was normalized in 1969.
The number 16655 was delivered from the factory with a three-axle bogie and put into operation as a prototype CC 10002. It was normalized in 1970.
commitment
The locomotives were all taken out of service between 2002 and 2011.
