Toavoid this heavy exf>ense, the road has established plantsfor reclaiming used roof sheets at M points on its systemwhere cars are repaired. In the great majority of instances, the wear in the originalmetal sheets was due to poor material supplied during thewar period, resulting in leaks occurring at the lower edge ofthe sheets at the eaves of the car where the sheets overlapthe flashing. The plan for reclaiming the sheets involvestheir removal from the car, cutting off tlie worn end, reform-ing and painting. The rooting sheets, now being reclaimed, originally were. of two lengths, 4 ft. 6j^ in. and 4 ft. H.^ in. IJolli length-liccts were Uhed with 4^ in, tlasliiiig. .\s reclaimed thet ft, (>)<i in. sheets are cut buck to a length of 4 ft. 3 in.■iiid used with 7 in, flashing if the wear in the original per-mits. Where the wear is greater the sheets are cut back toa length of 4 ft. 0 in. and used with 10 in. flashing. Sheetsi/riginally 4 ft. 8^ in. long when rcdaimed are cut back to 4 ft. 5yJ2 in. for use with 7 in. tlashing and to 4 ft. 23 j 10 in. flashing is used. Roof sheets which are not suitable for use with either the7 in. flashing or 10 in. flashing are squared and split in thecenter of the width after all defective metal has been cutoff the ends, and are then formed into 7 in. flashing. The10 in. wide flashing is made from new galvanized iron. The drawing showing the arrangement of the facilities in
