Underground electric haulage /
Underground Electric Haulage focuses on the locomotives used in modern mine railways. The locomotives of many different types are used for such underground operations as gathering at the loading points, shunting at the pit bottom, hauling man-riding vehicles, but primarily hauling material cars on t...
