Union Pacific

The Union Pacific West Line (UP-W) is a Metra commuter rail line operated by Union Pacific Railroad in Chicago, Illinois and its suburbs. Metra does not refer to its lines by particular colors, but the timetable accents for the Union Pacific/West line are "Kate Shelley Rose" pink, honoring an Iowa woman who saved a Chicago & North Western Railway train from disaster in 1881. In April 2013 the public timetable shows 30 trains leaving Chicago each weekday, of which 22 run to Elburn. All weekend trains run to Elburn. Of the 8 trains on weekdays that do not run through to Elburn, 4 terminate at Elmhurst, 2 at Geneva, 1 at West Chicago, and 1 at La Fox. All weekend trains run through to Elburn. Until 2006, all trains that terminated at Elburn today terminated at Geneva.

The Union Pacific / Northwest Line (UP-NW) is a commuter rail line provided by Metra and operated by the Union Pacific Railroad in Chicago, Illinois and its surrounding suburbs. While Metra does not refer to any of its lines by colors, the timetable accents for the Union Pacific/Northwest line are bright "Viking Yellow," honoring the Chicago & North Western Railway's Viking passenger train.

The Union Pacific / North Line (UP-N) is a Metra commuter rail line in the Chicago metropolitan area that runs between Chicago and Kenosha, Wisconsin. It is part of the Metra system, but it is operated by the Union Pacific Railroad (UP). (Metra does not refer to its lines by particular colors, but the timetable accents for the Union Pacific/North line are dark "Flambeau Green". The colors came from the company colors of the Chicago & North Western Railway, while "Flambeau" refers to the C&NW's Flambeau 400 passenger train.) This line was known as the Chicago & Northwestern/North Line until C&NW was absorbed by Union Pacific circa 1995.

The Union Pacific Railroad is a Class I line haul freight railroad that operates nearly 8,500 locomotives over 32,000 route-miles in 23 states west of Chicago, Illinois and New Orleans, Louisiana. The Union Pacific Railroad network is the largest in the United States and is serviced by more than 47,000 employees.
