To save the axles from the scrap pile we used ourelectric welding plant to fill in the grooves, as indicatedby No. 2 of Fig. 1, and then turned the axles down, as February 6, 1915] ELECTRIC RAILWAY JOURNAL 295 shown by No. 3 of Fig. 1. While this treatment addedto the life of the axles, the welded material also woreoff in time. The question of reclaiming these axles,therefore, came up a second time with the result thatwe decided to try the scheme of attaching a case-hardened collar on the end of the axles, as shown inFigs. 2 and 3. This collar consists of a piece of steelwhich is case-hardened to a depth of 1/16 in. in thegrooved part only. The axle is turned down at the endfor a distance of IS1, in. and chamfered for 3/16 the extreme end. The collar is
