Union Pacific's LUL57 local tops 5033 ft. York Summit on UP's Sharp Subdivision. The 11 car train, with two spiffy SD40Ns for power, made easy work of the seven mile 1% grade from CP C735, West Payson, topping the hill at 48 mph. The six box cars were picked up at Longview Fiber in Spanish Fork while the five covered hoppers will be set out at Ashgrove Cement (Martmar) in Leamington Canyon.
