The Fascinating Engineering That Powers Electric Trains!
One might be surprised to learn that in electric trains, energy from overhead lines ends up in the track grounding cable after circulating in the wheels. Three-phase power conversion, regenerative braking and zigzag overhead lines give electric train technology a unique character... We're going to look at all the engineering secrets that make electric trains work, by starting with the simplest possible design.
Intended to free itself from the constraints inherent in steam, electric traction requires the implementation of new technologies. The real revolution in this area came after the Second World War with the development of 25,000 volts/50 Hz single-phase alternating current traction. This episode takes you through the first large-scale electrification carried out in 1954-1955 by the SNCF with this current, on the Valenciennes-Thionville line supplying the North-East industrial basin.
Say hello to Alstom's battery solution for electric trains!
Battery operation makes it possible to fill in non-electrified track sections.
Our solution offers a modular number of battery packs for flexible range, regenerative braking for lower energy consumption, dynamic charging to recharge the batteries for even longer catenary-free operation. No additional catenary - or only a limited amount - is needed to minimize infrastructure investment. Our battery solution guarantees the lowest noise level for quiet sleep, and zero CO2 emissions for clean cities.
