[holding answer 9 January 2008]: The research referred to in the question was commissioned by the Rail Safety and Standards Board (RSSB). RSSB has no plans to publish any material relating to hammers. Having reached the conclusion that escape through windows of passenger trains should not be encouraged, RSSB concluded that the work on hammers should cease. There is therefore no final report or validated set of data relating to hammers. The final report on the overall approach to passenger containment, to which the hon. Gentleman refers in his question, is available on the RSSB website at:
The Department for Transport does not have any of the data requested.
