This modification can be applied to cars offrom 1 cu. yd. to 6 cu. yd. capacity. , Small cars of 1 cu. yd., lYz cu. yd. and 2 cu. yd. capaqityand of the end dumping style can be mounted on a swivel-base so as to dump in any position. (See Rotary DumpCars.) In the construction of the New York aqueduct a special-ly designed car of 40 cu. ft. capacity and 30 in. track gagewas used. The body was carried on rockers of a designsimilar to that used on many V-body dump cars. The doorswere hung at a considerable distance above the bottom ofthe bed so as to secure a wide opening, and to provide. Fig. 25—Small Box-Body Quarry Car for handling very large rocks the doors were designed sothat they could be easily lifted off. The same design hasalso been found quite useful in general quarry work. For use around industrial plants, in mines, for coalinglocomotives and for other purposes small box-body cars, ofspecial design and arranged to dump on the side or on theend have been found to be satisfactory. Hopper Bottom Cars Hopper bottom cars are suitable for use where the loadcan be dumped between the rails of the track. They areextensively employed in steam railroad service for handlingcoal, ore and other substances and are used in the industrialfieldfor moving such loose bulk materials as coal, ashes, coke,sand, gravel, crushed stone, earth, cinders, clay, shale, ores,soda ash, phosphates, fertilizer, etc. They
