Train protection system

A train protection system is a railway technical installation to ensure safe operation in the event of human error.[2] The Great Western Railway in the UK introduced its 'automatic train control' system in the early years of the 20th century.A bell rang in the locomotive's cab to confirm the clear aspect, and the electric current kept the brakes from being applied.One disadvantage of this kind of system is that the train cannot speed up before the signal if it has switched to green because the onboard computer's information can only be updated at the next magnet.This model allows adopters to meet the cost and performance requirements of disparate solutions, from the smallest to the largest.
