Show possible Jhe operating of trains through that part of Wyoming without with-out helper engines. The Ogdon-Lucin cut-off reduced the distance from Ogdcn to the coast 41 miles and increased the tonnage that one engine could pull between Ogden and Montcllo several hundred per cent. The Aspen tunnol and the Ogden-Lucin trestle across Great Salt Lake were two of Harriman'g most important cut-offs and, while both have presented vexatious weaknesses, they are today in course of being perfected, and will stand as monuments to the great railroad man's foresight, judgment and resourcefulness. TWO ENGINEERING FEATS. I 6 The Harriman engineers are not easily discouraged when they have a big problem to wor out. Of this we are reminded by the fact that a little army of men have been at work for two years cementing cement-ing the floor of the Aspen tunnel, just east of Evanston, Wyoming, where the big cut-off in the main line of the Union Pacific rail, road was made a few years ago when E. H. Harriman was cutting down grades, eliminating curves and reducing mileage. The Aspen tunnel is a mile and a quarter long. It was driven through a clay formation, through which seeped water and oil. The water, oozing through the floor of the tunnel, made a soft mushy foundation for the ties and rails and made impossible the building, by ordinary methods of ballasting, a safe and substantial roadway. The engineers, as a last resort, decided to concrete the entire tunnel tun-nel and for two years a gang of forty to fifty men, with a work, train has been excavating five feet below the old floor of the tunnel tb c0i,'d cement with the result that the two-thirds of the tunnel which has been finished is impervious to water, and as suic a, inough there was no water or oil or shifting formation to eontend against. At present trains are seventeen minutes passing through the abysmal darkness, but when the entire bore is concreted and the workmen are out of the way, this time will be reduced more than one half.
