Thenew rails were 7-in. Lorain section No. 91-375. Onerail of each track was roughly lined in, bolted andspiked. The other rail was then spiked to gage. Thespiking was done by a crew of four men. Two, withbars, held the tie up against the rail and the other twodrove the spikes with mauls. Ballasting with Pneumatic Tampers After the spiking was completed the rails were jackedup to grade, leaving space of about 7 in. between thebottom of the ties and the sub-grade. Crushed stone. ELMIRA TRACK RECONSTRUCTION—FIGS. 9 AND 10—TIE TAMP-ING WITH PNEUMATIC MACHINES; SELF-PROPELLEDCONCRETE MIXER ballast was then shovelled into place and tamped lightlyunder the ties with shovel and pick. The full length ofthe ties was tamped with the aid of the same pneuma-tic tools, which were employed for asphalt and concretecutting. For this work standard tamping bars with %-in. faces were used with the tools, and the menworked in pairs, one on each side of the tie (Fig. 9).By compacting the ballast from both sides simultane-ously none of the force of the blows was spent in shift-ing the ballast from side to side. Observations madeon one section showed that four machines tamped 340ties in twenty-six consecutive hours. The average timerequired for two men with the pneumatic tampers tocomplete the tamping operation of a single tie was fromsix to seven minutes. In tamping we operated with a gang of five fifth man sounded the ties and wat
