How do train tracks know when a train is coming?

In the US, the detection method is electrical, through the rails. The method is ever-evolving but began around the turn of the 20th century when a battery at the far end of the track sent current down the rails to the signal and was shunted when a train entered the circuit.

At age 62, I could push a train car down a track. Unlike a steam engine that would hammer the rails (a main reason why they were retired), modern railcars glide with low friction, and crushed rock underneath the tracks helps diminish impact. You won't hear it or feel it, Rangel says.

Maintenance: Trains may run at slower speeds at night to allow for track maintenance or repairs to be carried out more easily and safely. Schedule: Running trains at slower speeds at night can help to keep schedules on track, allowing trains to make up time lost during the day or to avoid delays caused by heavy.
