Enhancing the crashworthiness of Mark 1 rolling stock: Part 2 - validation of design modifications

摘要

Mark 1 rolling stock is known to be significantly less safe in a collision than more modern vehicles (1). A series of modifications have been designed in order to improve the crashworthiness of these carriages. The modifications can be divided into three categories: crush initiators, anti-overriding components and shear-out devices. This paper details the design validation testing programme which has included both static and dynamic testing. The work described in this paper has been sponsored by the Health and Safety Executive's Railway Inspectorate and has been undertaken under their direction.
