Pacer
Safety worries were raised after the 1999 Winsford crash. A Virgin Trains Class 87 express train ran into an empty First North Western Class 142 Pacer, after the Pacer had fouled the main line at Winsford, Cheshire on the West Coast Main Line. The wire straps that held the body of the Pacer to its frame broke, separating the body from the frame and causing severe damage. The unit was written off. Twenty-seven passengers and crew were wounded, four badly. But all passenger injuries were on the other train, as the Class 142 was running empty at the time.
