The same principle of capitalizing estimated economies inoperation and making the necessary investments to bringabout these economies is being applied on several other linesin the system. For instance, on the Moundsville line runningbetween Wheeling and Moundsville the company is entirelyreconstructing the track with heavier rails in order to permitof a faster schedule. It is also relocating the switches and. APPROACH TO STEUBENVILLE ON CUT-OFF the difficult nature of the work will be understood from thefact that in the stretch of two miles it was necessary tobuild in all 3000 ft. of retaining walls, equivalent to one-fourthof the total distance. These walls range from 100 ft. long tothe longest, which is 1600 ft. long, and from 9 ft. to 55 The heaviest walls were formed of mass concrete andthe lighter walls were built of masonry. The available location for the line also made necessary anumber of heavy fills, one in particular at a point known asCallagans Crossing probably being one of the heaviest fillsever undertaken in the construction of an electric gulch at this point required 30,000 cu. yds. of materialto bring the road to grade. To hold this filled material inplace a masonry retaining wall 250 ft. long and 35 ft. highwas built along the lower side. Another wall deserving ofmention on account of its dimensions and unusual cost inelec
