The River Subdivision or River Sub is a railway line along the Mississippi River that runs approximately 124 mi from Saint Paul, Minnesota south to La Crescent.
 U.S. Highway 61 closely parallels the route between La Crescent and Red Wing,MN.
 The line is operated by the Canadian Pacific Railway.
 BNSF Railway operates a complementary St. Croix Subdivision which traces the eastern side of the river in Minnesota and Wisconsin.
 The two routes share some track between Saint Paul and St. Croix Jct., near Hastings, Minnesota.
The Midway Subdivision or Midway Sub is a 12.4 mi railway line in Minneapolis and Saint Paul, Minnesota on the BNSF Railway's Northern Transcon which runs from Chicago, Illinois to Seattle, Washington and Portland, Oregon.
 This is former Great Northern Railway trackage, and now forms the southern set of BNSF tracks running between the two cities.
 The companion route running slightly to the north is the St. Paul Subdivision, former Northern Pacific Railway tracks.
 The Midway Subdivision hosted about 24 trains per day as of September 2015.
The Northern Transcon, a route operated by the BNSF Railway, traverses the most northerly route of any railroad in the western United States.
 This route was originally part of the Chicago, Burlington and Quincy Railroad, Northern Pacific Railway, Great Northern Railway and Spokane, Portland and Seattle Railway systems, merged into the Burlington Northern Railroad system in 1970.
Eola is an unincorporated community in Naperville Township, DuPage County, Illinois, United States.
 Although unincorporated, it has a post office, and has been given the zip code 60519.
 Eola is located near the western border of DuPage County, just north of Metra's BNSF Railway Line, and is surrounded by the city limits of Aurora.
 The community is the site of a BNSF Railway yard.
 Metra's BNSF Railway Line passes through the community but no longer stops there.
 A potential station would open on the STAR Line to transfer with the BNSF Line.
 In 2010, the population for Eola's zip code was 108.
The Hinckley Subdivision or Hinckley Sub is a railway line operated by BNSF Railway between Coon Rapids, Minnesota, and Boylston Junction between Foxboro and Superior, Wisconsin.
 Before the Burlington Northern merger of 1970, this line was formerly owned by Great Northern Railway.
 The line branches off to the north from the Staples Subdivision at Coon Creek Junction in Coon Rapids, and ends where it meets the Lakes Subdivision that brings the rails into Superior and Duluth, Minnesota.
 This is the only active rail line between Duluth–Superior and Minneapolis–Saint Paul, so the other Class I railroads operating in Minnesota, including Canadian Pacific, Canadian National and Union Pacific have at times acquired trackage rights on the route.
 As of May 2013, about 14 trains per day used the route.
The St. Paul Subdivision or St. Paul Sub is an 30.9 mi railway line running from Minneapolis through neighboring Saint Paul, Minnesota and on into Saint Paul's southeastern suburbs along the Mississippi River.
 It is a segment of BNSF Railway's Northern Transcon which runs from Chicago, Illinois to Seattle, Washington.
 Between Minneapolis and Saint Paul themselves, this route runs on former Northern Pacific Railway trackage, and now forms the northern set of BNSF tracks running between the two cities.
 The companion route running slightly to the south is the Midway Subdivision, though the St. Paul Subdivision is the busier set of tracks, hosting about 59 trains per day as of April 2009.
 It is the second-busiest rail line in the state, after the segment of the Staples Subdivision between Fridley and Coon Rapids.
The Chicago Subdivision or Chicago Sub is a railroad line in Illinois that runs about 38 mi from Chicago to Aurora and hosts Metra's BNSF Railway Line commuter service.
 It is operated by BNSF Railway as the easternmost part of the railroad's Northern Transcon to Seattle, Washington.
 This line is known as the Racetrack because it is mostly triple-tracked and supports fairly fast trains.
 It had been operated by a BNSF ancestor, the Chicago, Burlington and Quincy Railroad, which introduced high-speed "Zephyr" passenger trains in 1934 and ran many of them along this subdivision from Chicago to points west.
The BNSF Railway Line is a Metra commuter rail line operated by the BNSF Railway in Chicago and its surrounding suburbs.
 In 2010, the BNSF Railway Line continued to have the highest weekday ridership (average 64,600) of the 11 Metra lines.
 (Metra does not refer to its lines by particular colors, but the timetable accents for the BNSF line are "Cascade Green," like the paint of the Burlington Northern Railroad.)
 In July 2017, the public timetable (published October 9, 2016) showed 47 trains leaving Chicago each weekday, of which 31 run to Aurora.
 Of the 16 trains that do not reach Aurora, 5 terminate at Route 59, 1 at Naperville, 1 at Downers Grove-Main St., 5 at Fairview Avenue, 3 at Westmont, and 1 at Brookfield.
 The public timetable (published October 9, 2016) also showed 47 trains arriving in Chicago each weekday, of which 29 start in Aurora.
 Of the 18 trains that do not start in Aurora, 6 start at Lisle, 1 at Downers Grove-Main St., 7 at Fairview Avenue, 1 at Highlands, and 3 at Brookfield.
The V&S Railway (reporting mark VSR) is a shortline railroad that operates two disconnected lines in the U.S. state of Kansas.
 It is affiliated with A&K Railroad Materials, a scrap dealer whose primary business is buying marginal rail lines with the intent of abandoning them and selling the material as scrap for immediate cash.
 The company acquired its first line, a former Atchison, Topeka and Santa Fe Railway line between Medicine Lodge and a BNSF Railway junction at Attica, from the Central Kansas Railway in 2000.
 In 2006 it expanded its operations by acquiring from the Hutchinson and Northern Railway (reporting mark HN) a short segment of former interurban in eastern Hutchinson, where it interchanges with the BNSF Railway, Union Pacific Railroad, and Kansas and Oklahoma Railroad.
 The V&S also operates a line in Colorado as the Towner Railway, which began serving a former Missouri Pacific Railroad line that had most recently been the Colorado, Kansas and Pacific Railway in 2005.
 Other railroads under common control with the V&S are the out-of-service Kern Valley Railroad in Colorado, the Gloster Southern Railroad in Louisiana and Mississippi, the Grenada Railway and Natchez Railway in Mississippi, a portion of the former Rock Island from St. Louis to Union, Missouri operated by the Missouri Central and the Southern Manitoba Railway in Manitoba.
The Wayzata Subdivision or Wayzata Sub is a railway line that runs about 93 mi from Willmar to Minneapolis, Minnesota.
 Currently operated by BNSF Railway, this was part of the Great Northern Railway's transcontinental line from Minneapolis to Seattle, Washington.
 Today, BNSF's Northern Transcon travels up the Staples Subdivision instead, which is a more direct route to Fargo, North Dakota.
 As of May, 2011, the route is of moderate capacity and typically sees around 15 trains per day.
