    STAY ALERT. Trains can come from either direction at any time and can be very quiet. Around train tracks or in stations, obey all warning signs and signals and use caution when using headsets or cell phones. WATCH THE OVERHANG. Trains are wider than the tracks; never sit on the edge of a station platform. STAND AWAY FROM THE PLATFORM EDGE. Pay attention to painted or raised markings at the platform edge, and stay at least three feet from the train while it is coming in or out of the station. WHEN ON BOARD, HOLD ON. Hold on tight to poles or seats, and listen carefully to directions from the train operator or conductor.

  • Common Risks Managed by the Railway Safety - IRSC

    Train CollisionsDerailmentsLevel /Grade Crossings and TrespassRailway Staff RisksStationsSuicidesDangerous GoodsCollisions can occur between two or more trains or between trains and infrastructure. Collisions between passenger trains travelling in opposite directions at speed are very rare but the consequences are usually serious. Railways operate signalling systems with varying degrees of complexity to ensure the separation of trains. There have been several recent high-profile accidents involving head-on collisions in Germany and Spain. More common occurrences include low speed accidents in stations, depots and yards. Train collisions can have a number of causes: drivers passing signals at danger, faulty routing, speeding, division of trains, poor wheel-rail adhesion and technical and human errors in the signalling system. The introduction of train-borne moving block signalling such as ETCS may provide further safety benefits but also presents a number of technical challenges, particularly when transitioning between areas using different signalling systems. Train designers are also lowering...
