Most signalling systems use trackside signals to control the safe movement of trains and tell drivers what to do. A colour light signal shows different colours to authorise train movements.

In the modern CBTC systems the trains continuously calculate and communicate their status via radio to the wayside equipment distributed along the line. This status includes, among other parameters, the exact position, speed, travel direction and braking distance.
The railway signalling system used across the majority of the United Kingdom rail network uses lineside signals to control the movement and speed of trains. The modern-day system mostly uses two, three, and four aspect colour-light signals using track circuit – or axle counter – block signalling.
Railfans get used to the usual patterns of trains in their area, and use scanners to listen in on railroad dispatch frequencies. But it takes knowledge and practice to decipher what you hear on the scanner.
They cannot pass on the same track. If in single track territory, one train must go into a siding and wait for the other train. If the trains are traveling in opposite directions, this is called a “meet if they are traveling in the same direction, is is called a “pass.
As the outside wheel's circumference becomes larger it is able to travel a greater distance even though it rotates at the same rate as the smaller inside wheel. The train successfully stays on the tracks! In this activity you will test for yourself how train wheel shapes impact their ability to stay on track.
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.
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.
Conductors and engineers sleep at home or at a hotel at their away terminal. The operating crew of a train in the US can only be on duty for 12 hours and then must be relieved.
A crossover is a pair of switches that connects two parallel rail tracks, allowing a train on one track to cross over to the other. Like the switches themselves, crossovers can be described as either facing or trailing.
Over-fatigued drivers and utility workers present a hazard. Waving means you're at least half awake and alert enough to notice a fellow laborer and therefore respond safely if something unexpected happens.
A train driver, engine driver, engineman or locomotive driver, commonly known as an engineer or railroad engineer in the United States and Canada, and also as a locomotive handler, locomotive engineer, locomotive operator, train operator, or motorman, is a person who operates a train, railcar, or other rail transport ...
Fact #4: Trains Can Stop, But Not QuicklySo if you think a train can see you and stop in time, think again. Trains cannot stop quickly enough to avoid a collision, which is why vehicles should never drive around lowered gates or try to “beat” a train.
At night, the air near the ground can have a different temperature than air only a few hundred feet above1. This affects the transmission of sound waves. There is usually less ambient noise after dark, so the distant train sounds louder. As pointed out elsewhere, maybe the trains don't use the horn in daytime.
