![]() ![]() Operator errors such as incorrect setting of points, excessive speed and poor driving behaviour can also result in derailments as can track. Derailments are often related to technical failures such as poor track geometry, damaged or defective switches and crossings, wear and fatigue in the wheel-rail interface, vehicle suspension faults. They often involves just one train although further risks arise when a derailed train fouls an adjacent running line. ![]() DerailmentsÄerailments remain reasonably common although those leading to significant injury or loss of life are increasingly rare. Train designers are also lowering the consequences of accidents by improving the crashworthiness and occupant protection of vehicles. 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 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. More common occurrences include low speed accidents in stations, depots and yards. There have been several recent high-profile accidents involving head-on collisions in Germany and Spain. Railways operate signalling systems with varying degrees of complexity to ensure the separation of trains. Collisions between passenger trains travelling in opposite directions at speed are very rare but the consequences are usually serious. Collisions can occur between two or more trains or between trains and infrastructure. ![]()
