Due to heavy opposing traffic and a Form B work window on the Lynndyl Sub, Union Pacific's ZLAAHB-13 detoured via the Sharp and Provo Subdivisions on July 14, 2012. The Z train is pictured on former Rio Grande rails in the Jordan Narrows some 20 miles south of Salt Lake City. The ZLAAHD-13 began its journey at the Port of Los Angeles, CA and will interchange with the Norfolk Southern at Ashland Avenue Yard in Chicago, IL.
