A series of tests have been carried out to demonstrate the effectiveness of measures to improve the safety of rail vehicles in end-on collisions. In particular, the tests addressed the problems which cause most of the fatalities in end-on collisions, namely extensive vehicle collapse at the impact point and vehicle overriding. Break-away, velocity sensitive couplers and careful design of the vehicle ends to provide a controlled collapse during collision may be used to distribute the collision energy among a series of unoccupied sacrificial collapse zones along the length of the train. By this means, the extensive collapse of the vehicle structure at the impact point and corresponding fatalities due to crushing should be avoided. Similarly, a simple ribbed anti-climber attached to a collapsible vehicle endstructure may be used to prevent vehicle override, again with a large potential reduction fatalities. The above measures should result in very little extra vehicle cost and should significantly improve vehicle safety.
