Mine Cars

During recent years the designing of mine cars has become a very highly specialized art. Mechanical methods of mining, constantly increasing speeds of transportation and thin seams of coal have made it absolutely essential to develop low cars of maximum capacity. The producer of coal from thick seams, because of mechanical mining, which he is already employing or con- templating adopting, is now as much interested in low cars of high capacity, as is the thin seam operator. The mine car builder has been alert to this trend and is equipped with a specially trained corps of engineers and salesmen, who receive the necessary information from the producer and develop therefrom a suitable car design to fulfill the conditions.
