The headlight on this train helps it stand out at night. Trains include a variety of types of lights, for safety, illumination, and communicating train status. [1] The most universal type of light is the headlight, which is included on the front of locomotives, and frequently on the rear as well. [2]
Communications-based train control (CBTC) is a railway signaling system that uses telecommunications between the train and track equipment for traffic management and infrastructure control. CBTC allows a train's position to be known more accurately than with traditional signaling systems. This can make railway traffic management safer and more ...
A Metrolink locomotive decal on an MP36PH-3C saying it has positive train control. Positive train control (PTC) is a family of automatic train protection systems deployed in the United States. [1] Most of the United States' national rail network mileage has a form of PTC. These systems are generally designed to check that trains are moving ...
The first such systems were installed on an experimental basis in the 1910s in the United Kingdom, in the 1920s in the United States, and in the Netherlands in the 1940s. . Modern high-speed rail systems such as those in Japan, France, and Germany were all designed from the start to use in-cab signalling due to the impracticality of sighting wayside signals at the new higher train spee
From the 1850s until the middle of the twentieth century, train orders were telegraphed in Morse code by a dispatcher to a local station, where the orders would be written down on standardized forms and a copy provided to the train crew when they passed that station, directing them to take certain actions at various points ahead: for example ...
When the signal is at 'clear' or green ("off"), the electromagnet is energised. As the train passes, the permanent magnet sets the system. A short time later, as the train moves forward, the electromagnet resets the system. Once so reset, a bell is sounded (a chime on newer stock) and the indicator is set to all black if it is not already so.

Primarily, Kavach works on the principle of continuous supervision of the movement authority and is designed to maintain train speed within the specified limits and can automatically apply brakes to slow down or to bring the train to a complete standstill, in case the Loco Pilots violates the speed restrictions or fails to act in time to prevent Signal Passed At Danger (SPAD); thereby reducing ...
