#also if someone steals a train then that's the British Transport Police's problem not ours

Always Learning

Here at Network Rail, we are always learning new things about how the railways work, and about new problems that can happen. For instance, recently I learned that when solar storms induce electrical currents in wires, they also induce currents in track circuits, making them think that there's a train there when there isn't. So, sometimes if your train is delayed by a signal failure, it's because of the sun. Previously, we had no idea this could happen, we just thought that either someone had stolen a train or there were ghost trains.
