Ily tni-nns ot this constant grip, slipping on greasy rails Is avoided. It Is also possible, with electric traction, to apply tho maximum maxi-mum torqtio at once, and thus to bring a railroad train up to Ita greatoat apeed much more quickly than la possible pos-sible with steam traction. This advantage ad-vantage Is especially valuable on city lines, where stoppages aro frequent and dittanies botneen stations short. The l-honomtile 1r-AUrin.
