How are train tracks monitored?

A track monitoring system consists of settlement sensors and twist sensors. Settlement sensors are mounted parallel to the rails and typically linked together. Twist sensors are mounted parallel to the ties. The jumper cable connects the sensor bus to a data logger.

Is there CCTV on train tracks? Railroads, for most countries, are considered in the common interest and are generally protected by some federal or state security. However, in terms of surveillance, there is generally a mix of traditional security cameras and cameras that take colored still shots.

Yes, trains in the United States and many in Great Britain do feature a type of security camera inside the cabs and externally as well. Also called onboard surveillance cameras, there is a multitude of reasons why each type of train features them on its exterior and interior.

Learn about the Maglev track and see a diagram of a Magelev track. The magnetized coil running along the track, called a guideway, repels the large magnets on the train's undercarriage, allowing the train to levitate between 0.39 and 3.93 inches (1 to 10 centimeters) above the guideway [source: Boslaugh].

A low-voltage electric current is sent between the two rails via a series of relays like the ones in this photo. When a train approaches, the current runs through the train's metal wheels and axles instead of the relays. This short circuit activates the crossing signal.

Electricity is easily the most dangerous factor in stepping on the track – it's always switched on and nine out of ten people die when they're struck by it. You can't outrun a train. And even if you could, you wouldn't hear it coming, as today's trains almost silently reach speeds of 125mph.

Cross train tracks only at designated pedestrian or roadway crossings, and obey all warning signs and signals posted there. If you cross at any other place, you are trespassing and can be ticketed or fined. All train tracks are private property. Never walk on tracks; it is illegal to trespass and highly dangerous.
