ISOLATED MINING LINE HAS 'BIG' RAILROAD FEATURES

A molybdenum mining project in Colorado has involved building of a 14.4-mile double-track automated narrow gauge ore-hauling railroad which includes a 9.6-mile tunnel under the continental divide, third-longest railroad tunnel in the world. Six electrically operated unit trains will shuttle between mine and ore processing plant. Laser beam guidance controlled tunnel construction. The welded rails are laid on wood cross ties on the surface and on a concrete slab in the tunnel. Three piece rubber fasteners are used for securing the rails to the slab.
