Transnet Electric Units, Class 22E, Double High Voltage 3 kV DC and 25 kV AC, N0's 22-039 & 22-180 driving slowly across the trajectory from Pyramid South towards Brits due to railworks after a train last week derailed there
The Designer of these 22E Class is Zhuzhou Electric Locomotive Co and was built by Zhuzhou Electric Locomotive Co. Transnet Engineering
During 2015 a quantity of 359 was built
Loco brake Electro-pneumatic, regenerative & rheostatic
Regenerative brakes
Regenerative braking is an energy recovery mechanism that slows a vehicle or object by converting its kinetic energy into a form that can be either used immediately or stored until needed. In a nutshell, the electric motor is using the vehicle's momentum to recover energy that would be otherwise lost to the brake discs as heat. This contrasts with conventional braking systems, where the excess kinetic energy is converted to unwanted and wasted heat by friction in the brakes, or with dynamic brakes, where energy is recovered by using electric motors as generators but is immediately dissipated as heat in resistors. In addition to improving the overall efficiency of the vehicle, regeneration can greatly extend the life of the braking system as its parts do not wear as quickly.
