Which is the first Alstom battery electric train?
Electrification of trains takes on a new form – battery-electric versions can now replace diesel series-hybrids. Alstom announced this month its first contract for battery-electric regional trains in Germany for the Leipzig-Chemnitz route, which requires the train to cover 80 km (50 miles) of non-electrified track.
Can a train be powered by a battery?
Using batteries as a train’s power source has been tested in Germany at low speed and with light loads, using traditional lead acid batteries. It’s a tried and tested technology, so it’s cheap and reliable, but the batteries have a limited life and are made with corrosive liquids and precious materials.
