A 25 kV charging station for battery trains

Battery-powered trains are rapidly becoming the vehicle of choice for the replacement of diesel trains on non-electrified rail lines. Often there is not enough traffic on these lines to justify the expense of erecting overhead line equipment (OLE) along the track. In many cases, the train runs under OLE for part of its route where the battery train can charge via its pantograph. However, sometimes additional charging is required. While it is possible to erect additional kilometers of OLE for charging, it is more cost effective to charge the train via pantograph while stopped at a station using a very short length of overhead conductor rail and a 25 kV power supply.
