摘要

In 1988 British Rail suffered a multi-fatality accident involving the collision and destruction of several vehicles of the Mark 1 type construction, see Figure 1. Vehicle underframes climbing over each other and shearing through the body structural members caused the most severe damage. Subsequent to this accident research and development work was commissioned to establish the feasibility of providing additional strength into these Mark 1 coaches above the underframe and of preventing the underframe structures from climbing over each other during a collision. Whilst strengthening the body structure was found not to be feasible, providing a simple and relatively cheap means of anti-climb was developed and tested on full size vehicles. This paper describes the key steps taken in the design and development of this solution.
