Book Description
Excerpt from Mine Tracks Their Location and Construction: Treating Briefly on the Materials Used and the Principles Involved in the Design and Installation, With a Set of Rules for a Standard Practice The gradual displacement of animals by mechanical haulage as the motive power in mine transportation, the successive increases in the weight of the locomotives employed and the improvements in car journals and rolling stock, admitting of longer, heavier trains at relatively high velocities, are making imperative a closer attention to the track material used in mines. Short-radius curves are falling into disuse wherever traffic is at all heavy. These curves are frequently the limiting factor in the length of the trip. The long wheelbase of the motors is not adapted to them, they are the site of continual derailments, the haulage speed must be reduced at their approach, the cars cannot be pushed around them without danger of the bumpers "locking," their maintenance is excessive, and for many other reasons the use of sharp curves is questionable economy. The introduction of the steel car for mine transportation also demands a higher grade of trackwork than was required for the wooden car; the deficiencies of the roadbed, to which the semi-pliant material of the latter adapted itself, tends to loosen the construction of the more rigid steel car.
