Question to the Department for Transport:

To ask the Secretary of State for Transport, what assessment his Department plans will be made of the crashworthiness of any D78 London Underground train that is converted to mainline use.

The assessment of the “crashworthiness” of a train is a matter for the prospective operator of that train.

The “Crashworthiness” of rail vehicles is regulated and assessed by standards, laid down in the TSIs (Technical Specifications for Interoperability) and supported by ENs (Euro Norms, or standards). A vehicle’s compliance with these requirements is verified by an independent body, suitably appointed for the task.

There is no government proposal to convert D78 London Underground stock to mainline use.
