A WORKER killed by a runaway trolley on the West Coast Main line had complained about safety equipment, it has been reported.

Christine Waters, 50, said her husband Chris feared new helmets were "more of a danger than safety" because workers could not hear when wearing them.

Mr Waters and three other men died when the wagon - carrying sections of track - rolled down a hill from a yard near Tebay, in Cumbria early on Sunday morning.

Reports suggest the men could not hear the wagon approaching.

The men were named on Monday, as an inquiry into the cause of Sunday's accident began.

They were Darren Burgess, 30, and Colin Buckley, 49, from Carnforth; Gary Tindall, 46, of Tebay; and Chris Waters, 53, of Morecambe.

Investigators will look at how the trolley separated from its engine.

British Transport Police and the Health and Safety Executive will also look at why the men were not alerted, despite reports that colleagues tried to call them on mobile phones.
