RailRadar GPS (by RailYatri) is a live tracker allowing users to watch the movements of passenger trains running in India on an interactive map. All passenger trains in India are operated by state-owned Indian Railways. In the first release the location and status of trains shown on the map was typically 15 to 30 minutes delayed from real-time.
Track algorithm operation depends upon a track file, which contains historical track data, and a computer program that periodically updates the track file. [3] Sensors information (radar, sonar, and transponder data) is provided to the track algorithm using a polar coordinate system, and this is converted to cartesian coordinate system for the ...
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 ...
The median length of a U.S. freight train is roughly 5,400 feet (1,646 meters), or roughly 90 cars, with a small fraction exceeding 14,000 feet (4,267 meters). Trains include equipment from ...
A Doppler radar is a specialized radar that uses the Doppler effect ... and let escort fighter aircraft train guns on enemy aircraft ... and improved computer tracking.
Additionally, Kavach offers few Non-Signalling based Non-SIL features such as; providing protection from head-on, rear-end, and side collisions by estimating the length of the track that the train is occupying in a block section and identifying the track that the train is on. It can detect and stop the train in case of a rollback.
GE Transportation Systems' Incremental Train Control System (ITCS) is installed on Amtrak's Michigan line, allowing trains to travel at 110 mph (180 km/h). [51] The 2015 Philadelphia train derailment could have been prevented had positive train control been implemented correctly on the section of track that train was travelling. The overspeed ...
