		anileated 89 days ago \| parent \| context \| favorite \| on: The magic of through running Apparently 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?

This is common in London as the suburban rail network there is a mix of third rail and overhead lines.
