St. Louis Service Unit, a Synopsis


Union Pacific's St. Louis Service unit is comprised of 17 main and branch lines in Illinois and Missouri. Stretching from Yard Center in Chicago to the

north, Dexter, MO to the south, Salem, IL to the east and Jefferson City, MO to the west. These lines are predominantly old Missouri Pacific lines with the

exception of the Bloomington and Springfield Subdivisions. This line was Southern Pacific's SPCSL line (SP-Chicago-St. Louis), which originally belonged to

the Chicago & Alton Railway, later Illinois Central Gulf, and then short-lived regional railroad Chicago, Missouri & Western. This route has received

government funding for high-speed rail, hosting 10 Amtrak trains daily; eight Lincoln Service trains (four each direction) between St. Louis and Chicago and

two Texas Eagle trains (one each direction) between Chicago and San Antonio, TX. Once a decrepit line devoid of maintenance, this corridor was completely

overhauled, with over 250 miles of concrete ties, fresh ballast, new rail, signals, and now even decorative fencing on both sides of the tracks to prevent

trespassers from wandering in front of an Amtrak train travelling at 110 MPH. In addition to the Amtrak trains, UP uses this line as a priority corridor for

intermodal traffic to and from the new Global IV intermodal terminal in Joliet, IL.


One of the largest sources of business on the St. Louis Service Unit has always been coal transloading along the Mississippi and Ohio Rivers. In recent

years, the coal industry has shrunk considerably with the departure from fossil fuels and the push for clean energy. However, Union Pacific still operates

coal trains from the Powder River Basin in Wyoming to coal transload terminals at Cook (Metropolis, IL) on the Ohio River and Cora (Rockwood, IL) on the

Mississippi River. In addition, coal trains for electric utilities are delivered to AEP at West Labadie, MO, TVA at Chiles, KY, and Calvert City,

KY (delivered by PAL), Electric Energy at Joppa, IL, and NIPSCO at Wheatfield, IN (on Norfolk Southern). Currently, there is one active coal mine in the

southern Illinois coal fields on the the UP system. Peabody Coal's Coulterville Coal Company Gateway Mine in Coulterville, IL. This mine almost exclusively

serves NIPSO's (Northern Indiana Public Service Co.) Wheatfield, IN power plant with several trains per week. On a smaller scale, Gateway Mine also supplies

unit coal trains to Ingredion (formerly Corn Products) in Summit, IL, a suburb of Chicago, to power their massive food refinery complex. With the

diminishing coal indsutry, the St. Louis Service Unit has supplemented it's traffic volume with an increase in intermodal traffic. The opening of

Centerpoint Logistic's Global IV (also known as JIT - Joliet Intermodal Terminal) in Joliet, IL has generated many new intermodal trains serving southern

California, Houston, TX, and Dallas, TX. In addition the ramps at Yard Center (Dolton Intermodal), and Dupo move traffic to the same locations, as well as

across the border to Mexico.


One of the largest commodities on the service though, is the automotive business. UP has invested in Salem, IL as the hub for finished automobiles and auto

parts. The yard at Salem underwent a massive expansion project in 2015 and then transitioned to remote control operations in 2016. Salem gathers UP

automotive traffic from Yard Center and St. Louis (Alton & Southern Railroad) as well as interchange traffic from CSX at St. Elmo, IL, CN at Kinmundy, IL,

and NS at Sidney, IL. These carloads are then reclassified and trains originated for Spring (Houston), TX, Kirby (San Antonio), TX and Arlington (Ft.

Worth), TX.


Among other commodities, the rest of the traffic on the service unit is filled out with general freight moving south from Chicago to Little Rock, AR, Kansas

City and points beyond, as well as grain from the hundreds of midwestern grain elevators to feed mills in the south, and frac sand for the fracturing

process in the production of petroleum products. The list of UP train schedules in this section lists all scheduled trains that origiante, terminate or

traverse the service unit. Unit trains, such as coal and sand that are scheduled and run between the same two points, run regularly, or are contractually

binding, are listed. Other unit trains, such as grain, are not listed as many symbols are simply one-off versions.
