UK: 20 mph speed limit ordered for Severn Tunnel trains

Railtrack has been served with a Prohibition Notice by Britain's Health and Safety Executive (HSE) because of serious concerns that trains could be derailed in the tunnel. This follows 4 incidents recently where broken rails have been found. The track is said to be rusting badly due to the damp conditions.

The 4 mile long tunnel, built by Brunel in the 19^th Century carries the main line between England and Wales under the Severn Estuary. It is currently undergoing a multi-million pound maintenance programme.
