The resulthas been that the transportation of lumber loaded in opencars has in recent years been a source of considerable troubleand expense to the carriers. The shocks encountered inordinary serv-ice often cause lumber to shift. If anv portionof the load slides beyond the end of the car or comes within6 in. of the brake wheel the car must be taken out of thetrain and the lading reshaped to conform with the loading. A Load That Will Probably Check Short at Its Destination rules before it proceeds to its destination. The tonnage oflumber shipped in open top cars is large and the loss in-volved in this switching and reshaping of loads is a consid-erable item. Some idea of the trouble experienced in haul-ing lumber in o|)en to() cars can l;e gained by examining theillu-trations which accomjiany this article. All the photo- 16 RAILWAY MECHANICAL EXGIXEER Vol. 92, No. 1 graphs of shifted loads which aro shown were taken at oneyard in a single week. The Illinois Central a short lime ago conducted a specialinvestigation in order to determine the loss of service fromcars due to the reshaping of loads which had shifted intransit. During a period of three months this road handled7,926 cars loaded with dressed lumber. The total car daysdelay on these shipments amounted to 17,778, an averageof days per car. Had it been possible for the IllinoisCentral to avoid the del
