lishedby fastening one end of a cable to the locomotive and attach-ing the other end to a plow that was mounted on the top ofa flat car at the other end of the train. The engine was thencut off from the train and moved ahead pulling the plow overthe string of flat cars. The cars had to be anchored to the 193 track which was hard on the ties, rail and track fittings, sothis method was soon discarded in favor of a steam operateddrum, which was mounted on a car at the opposite end of thetrain from the plow. This drum as it wound up the cabledrew the plow along the train. Due to numerous reasons, perhaps the most importantof which was the small amount of dirt that could be loadedon each car, about 16 to 20 cubic yards, this method gradu-ally became obsolete and the present conventional type ofoperation came into favor. This method consists in mounting the ditcher on a flatcar placed between two side dump cars. As the capacity ofthese cars is limited to the dumping radius, or reach, of the

ditcher, not over 16 to 20 cubic yards can be loaded in eachcar. As the loading is confined to two cars it will be seenthat after loading 40 cubic yards per ditcher, a run to thedumping ground must be made. The average loading of asingle ditcher may be from 280 to 300 cubic yards per day,from which it is evident that seven dump runs, at least, mustbe made. Operating two or more ditchers together will re-duce the time to finish a given job and also reduce the num-ber of work trains required, it also reduces the number ofdump runs. As previously stated the limited dumping radius of themounted type ditcher prevented the railways from taking ad- 194 vantage of the improvements that have been taking place inthe character of dump cars used in construction service. Onconstruction, the cuts being more extensive, the shovels areworked on the ground loading the material excavated intocars drawn past on an adjacent track. Economy in car con-struction dictated the use of longer cars which were th
