Railway signalling (BE), or railroad signaling (AE), is a system used to control the movement of railway traffic. Trains move on fixed rails , making them uniquely susceptible to collision . This susceptibility is exacerbated by the enormous weight and inertia of a train, which makes it difficult to quickly stop when encountering an obstacle.
This advanced system features modern signaling with virtual blocks and Automatic Train Operation (ATO) functionality over an LTE backbone. A standout feature of the RRTS is the interoperability across all corridors, enabled by ETCS Level-2. The system monitors train speed and direction while providing operational directives via a radio block ...
The token system is still regularly used on the present-day State Railway of Thailand system. Although most use occurs in regional areas, some use appears in the capital city, Bangkok, such as the Makkasan to Khlong Tan section etc. [16] Sri Lanka Railways uses a tablet exchanging system on the up-country railway line.
The US and Canada departed from UK practice wherein a semaphore blade is devoted to each route (Route Signaling). General North American practice is to group routes by speeds and use a single blade for, say, "medium speed" regardless of the number of routes involved (Speed Signaling). The primary exception to this situation is in the field of ...
A diverging route might have a significantly lower permissible speed than the main route, and if the route taken was not the one expected, it could result in derailment. There are two methods of junction signalling. Signalling in the UK uses route signalling. Most railway systems around the world, however, use speed signalling.
The ACD Network is a train-collision prevention system invented by Rajaram Bojji and patented by Konkan Railway Corporation, a public-sector undertaking of the Ministry of Railways, government of India. Anti-collision devices were found to be effective in the Southern Railway zone after a brief trial. [citation needed]
CBTC is a signalling standard defined by the IEEE 1474 standard. [1] The original version was introduced in 1999 and updated in 2004. [1] The aim was to create consistency and standardisation between digital railway signalling systems that allow for an increase in train capacity through what the standard defines as high-resolution train location determination.

On a rail transport system, signalling control is the process by which control is exercised over train movements by way of railway signals and block systems to ensure that trains operate safely, over the correct route and to the proper timetable.
