How do trains know when to stop?

The railways use a train detection systems which can tell signallers exactly where every train is and how fast they are going. There are also systems that can automatically stop trains if the driver doesn't take the correct course of action or passes through a red signal.

a magnet on the track, when the train runs over the magnet it will warn the driver to stop; a transmission loop that tells the train the signal is red, this will trigger the train computer to apply the brake.

Trackside signals control entry into and out of each block and also warn trains when the line ahead might be occupied and if they must reduce speed. Just like on a road, there are also speed limit signs, reducing speeds in built up areas and where there are hazards.

Trains can't stop quickly or swerve. The average freight train is about 1 to 1¼ miles in length (90 to 120 rail cars). When it's moving at 55 miles an hour, it can take a mile or more to stop after the locomotive engineer fully applies the emergency brake.

The position of the train driver differs from that of the conductor in that the former is in charge of running the locomotive while the latter manages the cars, including the crew, passengers and their activities.

Engines may be left idling to maintain important safety related functions such as maintaining engine temperature, air pressure for the brake system, the integrity of the starting systems, the electrical system and providing heating or cooling to a train's crew and/or passengers.

The signalling system is used to direct a train on to a particular route. A train follows set routes along the tracks, with the signalling system often used to communicate these routes to the driver.

Other than a refrigerator/watercooler and a bathroom there are almost zero ammenities on a locomotive. Only way a engineer can go to bathroom is by stopping his train or if the conductor is a certified engineer he could run for while.

Sometimes, the trains can stop in the middle because of technical or mechanical problems with locomotives or picking or dropping off the freight cars at the industrial tracks. They can also stop in the middle because they are waiting for the section ahead of them to get clear of a train occupying it.

In a major train derailment, the train will often come off the tracks completely. Depending on where the derailment occurs, its momentum may cause it to collide into compartments ahead of the compartment that became derailed. If any passengers are onboard, this can result in serious injuries.
