The Northern Pacific Railway (reporting mark NP) was a transcontinental railroad that operated across the northern tier of the western United States, from Minnesota to the Pacific Northwest.
 It was approved by Congress in 1864 and given nearly 40000000 acre of land grants, which it used to raise money in Europe for construction.
The Winnipeg Limited was an overnight named passenger train operated by the Great Northern Railway 457 mi between St. Paul-Minneapolis and Winnipeg, Manitoba.
 It competed on the route with the overnight "Winnipeger" of the Minneapolis, St. Paul and Sault Ste. Marie Railway (“Soo Line”), and the Northern Pacific Railway’s unnamed daytime passenger train.
The New Mexican Railway Company was incorporated in the Territorial Legislature of New Mexico on Feb 2, 1860, prior to the beginning of the American Civil War.
 Corporate members were Henry Connelly, Antonio J. Otero, who served as a justice of the New Mexico Territorial Supreme Court; Ambrosio Armijo (the father of Colonel Perfecto Armijo); José Felipe Chavez, Francisco Chavez; Spruce M. Baird, a judge sent by Texas during the U.S. provisional government of New Mexico to organize their claimed land east of the Rio Grande as the Santa Fe county of Texas; Francisco Perea, José Leandro Perea, who was the uncle of Francisco, Charles B. Clark, José Guadalupe Gallegos, Stephen Boice, William H. Moore, Ceran St. Vrain, Thomas C. de Baca, Merrill Ashurst, Duff Green, John Titus, David R. Porter, Oliver W. Barney, and Philip L. Fox.
 The "Memorial of the New Mexican Railway Company, in Relation to the Pacific Railroad" was introduced by Miguel Antonio Otero in the United States Congress on May 21, 1860.
 It was an argument in favor of the southern route for a transcontinental railroad.
 Arguments over the central vs. southern route were a part of the complex of insoluble relations between states, dating back to James Gadsden's involvement in 1845 (as described in the discussion under the Gadsden Purchase).
 These arguments contributed to the outbreak of the American Civil War.
 The New Mexican Railway Company was formed in conjunction with the attempt to retain rights of in-state railroad construction oversight within the Territorial government.
 The act of incorporation stated that company rights and privileges would be forfeited if construction had not begun within a period of five years.
 Beginning in 1862, after the outbreak of Civil War, the Union Pacific Railroad and the Central Pacific Railroad of California were granted lands and construction privileges for the First Transcontinental Railroad project under the Pacific Railway Acts.
 Construction of this Overland Route was begun in 1863 and completed in 1869.
 The southern route did not become a reality until 1883, when the Southern Pacific Railroad linked New Orleans and the Gulf of Mexico with Los Angeles and the Pacific Ocean.
The Niles Canyon Railway (NCRy) is a heritage railway running through Niles Canyon, between Sunol and the Niles district of Fremont in the East Bay of the San Francisco Bay Area, in California, United States.
 The railway is listed on the National Register of Historic Places as the Niles Canyon Transcontinental Railroad Historic District.
 The railroad is operated and maintained by the Pacific Locomotive Association which preserves, restores and operates historic railroad equipment.
 The NCRy features public excursions with both steam and diesel locomotives along a well-preserved portion of the First Transcontinental Railroad.
 The Golden Gate Railroad Museum moved its collection from San Francisco to the NCRy in 2007 for storage and limited operations after their home at Hunters Point Naval Shipyard was shut down for redevelopment.
The Royal Blue was the Baltimore and Ohio Railroad (B&O)'s flagship passenger train between New York City and Washington, D.C., in the United States, beginning in 1890.
 The Baltimore-based B&O also used the name between 1890 and 1917 for its improved passenger service between New York and Washington launched in the 1890s, collectively dubbed the Royal Blue Line.
 Using variants such as the "Royal Limited" and "Royal Special" for individual "Royal Blue" trains, the B&O operated the service in partnership with the Reading Railroad and the Central Railroad of New Jersey.
 Principal intermediate cities served were Philadelphia, Wilmington, and Baltimore.
 Later, as Europe reeled from the carnage of World War I and connotations of European royalty fell into disfavor, the B&O discreetly omitted the sobriquet "Royal Blue Line" from its New York passenger service and the "Royal Blue" disappeared from B&O timetables.
 Beginning in 1917, former "Royal Blue Line" trains were renamed: the "Royal Limited" (inaugurated on May 15, 1898), for example, became the "National Limited", continuing west from Washington to St. Louis via Cincinnati.
 During the Depression, the B&O hearkened back to the halcyon pre-World War I era when it launched a re-christened "Royal Blue" train between New York and Washington in 1935.
 The B&O finally discontinued passenger service north of Baltimore on April 26, 1958, and the "Royal Blue" faded into history.
The Pacific Railroad Acts were a series of acts of Congress that promoted the construction of a "transcontinental railroad" (the Pacific Railroad) in the United States through authorizing the issuance of government bonds and the grants of land to railroad companies.
 Although the War Department under then Secretary of War Jefferson Davis was authorized by the Congress in 1853 to conduct surveys of five different potential transcontinental routes from the Mississippi ranging from north to south and submitted a massive twelve volume report to Congress with the results in early 1855, no route or bill could be agreed upon and passed authorizing the Government's financial support and land grants until the secession of the Southern states removed their opposition to a central route.
 The Pacific Railroad Act of 1862 (12 Stat.
 489) was the original act.
 Some of its provisions were subsequently modified, expanded, or repealed by four additional amending Acts: The Pacific Railroad Act of 1863 (12 Stat.
 807), Pacific Railroad Act of 1864 (13 Stat.
 356), Pacific Railroad Act of 1865 (13 Stat.
 504), and Pacific Railroad Act of 1866 (14 Stat.
 66).
The Erie Limited was a streamlined passenger train operated by the Erie Railroad between Jersey City, New Jersey (for New York City) and Chicago, Illinois via the Southern Tier.
 It operated from 1929 to 1963.
 After the merger of the Erie and the Delaware, Lackawanna and Western Railroad (DL&W) in 1960 it was known as the Erie-Lackawanna Limited.
 Once the premier passenger train on the Erie, repeated service reductions in the 1950s and 1960s left it a shell of its former self.
 The "Phoebe Snow" replaced it in 1963.
The Kansas Pacific Railway (KP) was a historic railroad company that operated in the western United States in the late 19th century.
 It was a federally chartered railroad, backed with government land grants.
 At a time when the first transcontinental railroad was being constructed by the Central Pacific and the Union Pacific, it tried and failed to join the transcontinental ranks.
 It was originally the "Union Pacific, Eastern Division", although it was completely independent.
 The Pennsylvania railroad, working with Missouri financiers, designed it as a feeder line to the transcontinental system.
 The owners lobbied heavily in Washington for money to build a railroad from Kansas City to Colorado, and then to California.
 It failed to get funding to go west of Colorado.
 It operated many of the first long-distance lines in the state of Kansas in the 1870s, extending the national railway network westward across that state and into Colorado.
 Its main line furnished a principal transportation route that opened up settlement of the central Great Plains, and its link from Kansas City to Denver provided the last link in the coast-to-coast railway network in 1870.
 The railroad was consolidated with the Union Pacific in 1880, and its mainline continues to be an integral part of the Union Pacific network today.
Empire Express: Building the First Transcontinental Railroad is a book written by David Haward Bain, published in 2000.
 It follows the initial conception of the idea of a transcontinental railroad, during the two decades before the Civil War, to the work of the engineers and entrepreneurs who fixed the route, assembled financing, drafted a work force and launched the two lines toward the eventual meeting point at Promontory Summit, Utah, in 1869.
 The story alternates between the Union Pacific driving west from Omaha and the Central Pacific blasting through the mountains from California.
The Overland Route was a train route operated jointly by the Union Pacific Railroad and the Central Pacific Railroad / Southern Pacific Railroad, between Council Bluffs, Iowa / Omaha, Nebraska, and San Francisco, California over the grade of the First Transcontinental Railroad (aka the ""Pacific Railroad"") which had been opened on May 10, 1869.
 Passenger trains that operated over the line included the "Overland Flyer", later renamed the "Overland Limited", which also included a connection to Chicago.
 Although these passenger rail trains are no longer in operation, the Overland Route remains a common name for the line from California to Chicago, now owned entirely by the Union Pacific.
