    The first pair, the Overspeed Sensor System (OSS), is sited at a position determined by line speed and gradient. The loops are separated by a distance that should not be traversed within less than a pre-determined period of time of about one second if the train is running at a safe speed approaching the signal at danger.

    en.wikipedia.org/wiki/Overspeed

    Mechanical overspeed protection is in the form of sensors. [6] The system relies on the centripetal force of the shaft, a spring, and a weight. [ 6 ] At the designed point of overspeed, the balance point of the weight is shifted, causing the lever to release a valve that makes the trip oil header to lose pressure due to draining. [ 6 ]

    The 'Overspeed Sensor System' pair of loops is located on the approach to the signal, and will activate the train's emergency brake if it approaches faster than the 'trigger speed' when the signal is at danger.

    Transmission Voie-Machine (TVM, English: track-to-train transmission) is a form of in- cab signalling originally deployed in France and is mainly used on high-speed railway lines. TVM-300 was the first version, followed by TVM-430. TVM-300 was developed in the 1970s as part of the TGV project. At speeds faster than 220 kilometres per hour, TGV ...

    Incident. At 17:25 GMT on 7 March 2015, a charter train approached Wootton Bassett Junction, where the Great Western Main Line and South Wales Main Line diverge at Royal Wootton Bassett, Wiltshire. In the approach to signal SN43, an Automatic Warning System (AWS) magnet was present in the trackbed, warning of a temporary speed restriction ahead ...

  7. Advanced Civil Speed Enforcement System - Wikipedia

    en.wikipedia.org/wiki/Advanced_Civil_Speed...

    Lack of a second speed limit below signal speed indicates ACSES is not in service. Advanced Civil Speed Enforcement System (ACSES) is a positive train control cab signaling system developed by Alstom. [1] The system is designed to prevent train -to-train collisions, protect against overspeed, and protect work crews with temporary speed ...
