OAK CREEK, Wis. — With Precision Scheduled Railroading in effect at Union Pacific, longer trains have become more frequent across its system. This loaded coal train is one such example. Loaded as two trains at North Antelope mine in Wyoming, Union Pacific consolidated both trains at South Morrill, Neb., for the trip to Oak Creek, just south of Milwaukee. The train, with symbol CNAOK 21, is passing Zion, Ill., on UP’s Kenosha Subdivision. It has six locomotives, SD70ACe No. 8991, SD70M No. 4903 on the front, SD70ACe No. 8734 and AC4400CWs Nos. 5799 and 5719 mid-train and AC4400CW No. 5902 on the rear. The train has 270 loads totaling 38,475 tons and stretching 15,025 feet.
