Cleveland 14 ELECTRIC RAILWAY JOURNAL [June 30, 1917 How the Lackawanna Oeseaming Processeliminates two very serious rail faults Greater Safety througn removal ot allseamy metal from thevital part of the base The weak, partially decarburized surfacesteel of the original ingot is ordinarily fin-ished into the rail, but if hot-milled off thepartially formed rail section, at the loca-tions of rail head and base, the finishingrolls complete their work upon clean, solidhigh-carbon steel and produce a harder,denser and finer finish. This, in short, ex-plains how the Lackawanna DeseamingProcess eliminates seamy bases and softwearing surface. Typical base seam—the kindthat tends to open up andcause Rail head sloughed offunder the cold-rollingaction of the wheels. TREATMENT of the partially finished rail bar as described above is the onlyrecent real improvement in rail manufacture—and is the most logical way ofmeeting present day increases in wheel load. This is proven by the markedresistance to wear and freedom from fracture, which Lackawanna Deseamed Railshave demonstrated in several years of service. Etching away the head and base surfaces of rails made by this process showsan entire freedom from seamy, streaky metal at these locations, and hardnesstests also prove that the metal here is slightly superior to that in the body ofthe rail. This deseaming process, as originated and controlled exclusively by us, is nowapplied (see picture below) to all Lackawanna Sections of 50 pounds per yardand over. Those seeking safer track, greater load capacity and reduced maintenanceexpense can profitably study our illustrated book on The Lackawanna DeseamingProcess, which we will mail on
