The St. Louis–San Francisco Railway (reporting mark SLSF) , also known as the Frisco, was a railroad that operated in the Midwest and South Central U.S. from 1876 to April 17, 1980.
 At the end of 1970 it operated 4547 mi of road on 6574 mi of track, not including subsidiaries Quanah, Acme and Pacific Railway or the Alabama, Tennessee and Northern Railroad; that year it reported 12,795 million ton-miles of revenue freight and no passengers.
 It was purchased and absorbed into the Burlington Northern Railroad in 1980.
 Despite its name, it never came close to San Francisco.
South Central Florida Express, Incorporated (reporting mark SCXF) (originally known as the South Central Florida Railroad (reporting mark SCFE) and run by the Brandywine Valley Railroad until September 17, 1994) is a short line railroad in southern Florida run by US Sugar Corporation.
 It serves customers at 26 locations.
Founded in 1996, the Naugatuck Railroad is a common carrier railroad owned and operated by the Railroad Museum of New England on tracks leased from the Connecticut Department of Transportation.
 The original Naugatuck Railroad was a railroad chartered to operate through south central Connecticut in 1845, with the first section opening for service in 1849.
 In 1887 the line was leased by the New York, New Haven and Hartford Railroad, and became wholly owned by 1906.
 At its greatest extent the Naugatuck ran from Bridgeport north to Winsted.
 Today's Naugatuck Railroad runs from Waterbury to the end of track in Torrington, Connecticut.
 From Waterbury south to the New Haven Line, Metro-North Railroad operates commuter service on the Waterbury Branch.
The Missouri Pacific Railroad (reporting mark MP) , commonly abbreviated MoPac, with nickname of The Mop, was one of the first railroads in the United States west of the Mississippi River.
 MoPac was a Class I railroad growing from dozens of predecessors and mergers, including the St. Louis, Iron Mountain and Southern Railway (SLIMS), Texas and Pacific Railway (TP), Chicago and Eastern Illinois Railroad (C&EI), St. Louis, Brownsville and Mexico Railway (SLBM), Kansas, Oklahoma and Gulf Railway (KO&G), Midland Valley Railroad (MV), San Antonio, Uvalde and Gulf Railroad (SAU&G), Gulf Coast Lines (GC), International-Great Northern Railroad (IGN), New Orleans, Texas and Mexico Railway (NOTM), Missouri-Illinois Railroad (MI), as well as the small Central Branch Railway (an early predecessor of MP in Kansas and south central Nebraska), and joint ventures such as the Alton and Southern Railroad (AS).
The Kansas City Southern Railway Company (reporting mark KCS) , owned by Kansas City Southern, is the smallest and third-oldest Class I railroad in North America (just behind Union Pacific Railroad and Canadian Pacific Railway) still in operation.
 Founded in 1887, KCS currently operates in 10 central U.S. states.
 KCS also owns and indirectly operates Kansas City Southern de México (KCSM) in the central and northeastern states of Mexico, and is the only Class I Railroad to own any track both inside and outside of Mexico's boundaries (Ferromex is the only other Class I operating in Mexico).
 KCS owns about 9,600 kilometers (6,000 route miles) of track, including trackage owned by subsidiaries.
Sublette is a railroad town in northern Rio Arriba County, New Mexico, built as a section station in 1880.
 It is located north-east of Chama, just south of the Colorado state line and at milepost 306.1 of the former Denver and Rio Grande Western Railroad.
 When the Denver & Rio Grande Western Railroad abandoned its narrow gauge lines in the late 1960s, two parts of the system were preserved independently: the Cumbres & Toltec Scenic Railroad from Antonito to Chama, including Sublette itself, and the Durango and Silverton Narrow Gauge Railroad.
 Sublette sits at an elevation of 9,281 feet in the southeastern San Juan Mountains.
The Milwaukee Road, officially the Chicago, Milwaukee, St. Paul and Pacific Railroad (reporting mark MILW) , was a Class I railroad that operated in the Midwest and Northwest of the United States from 1847 until 1980, when its Pacific Coast Extension was embargoed in the states of Montana, Idaho, and Washington.
 Its core Midwest system was merged into the Soo Line Railroad on January 1, 1986.
 The Pacific Coast Extension from the Midwest to the Pacific Northwest, planned between 1901 and 1906 and built between 1906 and 1909, was carried out under the auspices of the "Chicago, Milwaukee and Puget Sound Railroad."
 This corporate entity was folded into its parent company in 1912.
The Holly Grove Historic District encompasses the historic central business district of Holly Grove, Arkansas.
 It covers about one block of Arkansas Highway 86, between Pine and Smith Streets, extending slightly in each direction beyond.
 The road is at this point divided by a median that formerly carried a railroad right of way, and was historically known as Main Street; the westbound lanes are now called Dr. Herd E. Stone Street, and the eastbound lanes Ralph Abramson Street.
 The district includes a collection of one and two-story brick buildings, most with vernacular commercial styling typical of the 1920s.
 The town grew as a railroad town beginning in the 1870s, its success spurred in part by a successful railroad tie-making business.
Monett was created as a railroad town by the St. Louis–San Francisco Railway ("Frisco Line") which came through in 1870 and would build branch going off the main line to Paris, Texas.
 Both lines are still in existence and operated by the BNSF Railway.
 During this time the area went through several names including Kings Prairie Depot, Plymouth, Plymouth Junction (when the southern branch was built in 1880), Gonten (named for the local post master because the Post Service said there were other Plymouths); and finally Monett in 1887 when the area was formally platted and the Monett name was applied to the post office.
 It was named for Henry Monett who was a popular general station agent for various railroads including the New York, Chicago and St. Louis Railroad ("Nickel Plate Railroad") before becoming an agent for the New York Central Railroad shortly before his death at the age of 35 in 1888.
