Fire safety testing of conveyor belts
(Figures supplied by British Coal) 8 The first major accident involving the use of locomotives occurred at Silverwood Mine in 1966. The driver of a diesel locomotive, hauling a train of material cars on a descending gradient of 1 in 26 (3.8%) found no retarding response when he applied the service brakes.
