Typically trains are powered from above, and subways are powered from the rails. Perhaps this is the distinction, rather than running underground.

- robjan 1y agoReally depends on the region and any pre-existing constraints at the time of electrification. A better distinction is probably rapid transit (metro, subway, the Tube, MTR/MRT) vs commuter rail.
- stronglikedan 1y agoTypically, trains power themselves.
- anileated 1y agoApparently in the US there are trains that use dual rail and overhead power, one for subway and another for overground portions. I suppose a subway train with rail only supply that goes overground sometimes is more dangerous because it is easier to accidentally step on a rail and rail is powered?
- laurencerowe 1y agoThis is common in London as the suburban rail network there is a mix of third rail and overhead lines.
