Coaling Station with Locomotive Hoist. — A design borrowedfrom the Baltimore & Ohio in which the pockets rest nor-mally at ground level while being filled and are then hoistedby locomotive power to an elevation suitable for loading thetender by gravity flow, Fig. 224. The design is very simple,consisting of an upright framework of 12 X 12 timbers, toserve as guides for the pocket, with a hoisting sheave at the topand another at the bottom. The movable pocke
