Abstract: At approximately 9:39 p.m. on November 22, 1999, Employee #1, an apprentice locomotive operator, with no underground experience, stepped off the locomotive to check the rear muck car. The locomotive began rolling forward, towards the portal. Employee #1 was struck by the moving locomotive and trailing muck cars. The employee fractured his right knee and leg, and received multiple pelvis fractures. Employee #1 was transported to the hospital, where orthopedic surgeons reconstructed the leg and knee. The locomotive was not equipped with a throttle or directional control that would return the engine to idle or shut off the power automatically when released by the operator. Additionally, the locomotive did not have a fail-safe secondary braking system.
