Single-phase power may be used for electric railways; the largest single-phase generator in the world, at Neckarwestheim Nuclear Power Plant, supplied a railway system on a dedicated traction power network.

The MR-73's current chopper recuperates energy when in braking mode, turning traction motors into generators and sending a regulated current back into the traction power supply for other trains to use.
43.
Due to this, if a train were to be travelling too slow and were to attempt to manoeuvre along these gaps the train would eventually lose traction power and slow down.
44.
The original traction power train consisted of a Leyland TL11 200 HP engine, a Self-Changing Gears mechanical automatic gearbox and a Gmeinder final drive unit on each car driving only one axle.
45.
In July 2015 it was announced that the traction power supply for the Olmedo-Pedralba de la Prader�a ( near Puebla de Sanabria ) section would be switched on on 7 August 2015.
46.
The power modules use water-cooled IGBT technology and provide about of traction power plus of HEP, an improvement over the HEP capacity of the original DC units, and enough for 18 Amfleet or Viewliner coaches.
47.
De Tochten is part of the section where traction power is received from overhead wires, although trains have to switch back to third rail power just east of the station for their journey to Nesselande.
48.
So just a small percentage increase in circumferential velocity due to slip can translate into a loss of traction power which may even exceed the power loss due to basic ( ordinary ) rolling resistance.
49.
This emergency trip system ( ETS ) immediately shuts down the traction power supply in the adjacent track section, to protect people already on or about to enter the track from the dangers of electric current.
50.
Ultimately, this plan was shelved as economically infeasible and the electrical traction infrastructure was left largely unchanged with the exception of a general traction power voltage increase to 12 kV and a corresponding transmission voltage increase to 138 kV.
