The Chicago, Burlington & Quincy was the Burlington Route, reporting mark CBQ. From a twelve-mile Aurora Branch it became the granger that also reached Denver, the Twin Cities, Billings, and, through the Colorado & Southern and the Fort Worth & Denver, the Gulf. Its slogans were Everywhere West and, once the stainless trains were famous, Way of the Zephyrs. The company itself did not go through bankruptcy. At 12:01 a.m. on March 2, 1970 it entered the Burlington Northern with the Great Northern, the Northern Pacific, and the Spokane, Portland & Seattle.
The railroad is remembered for those Zephyrs, and for a steam fleet built in its own shops as often as it was bought.

The Galena & Chicago Union, chartered in 1836, was open from Chicago to Elgin by January 1850 and reached Freeport in September 1853. Aurora wanted its own railroad. The Illinois legislature chartered the Aurora Branch Railroad on February 12, 1849, and the company was organized on February 22. The line was to run up the Fox River to Batavia and then to Turner Junction, now West Chicago, and use the Galena & Chicago Union into the city.
Grading was underway in the spring of 1850. Track reached Batavia on August 22. On September 2, 1850 the Aurora Branch held its opening, with a borrowed locomotive and coach. The engine was the 4-2-0 Pioneer, the first locomotive to operate out of Chicago, on October 24, 1848. Rails were into Aurora on October 4, and regular service over the Galena road into Chicago began on October 21, 1850.

On June 22, 1852 the company became the Chicago & Aurora Railroad. The new aim was west, toward a connection about fifteen miles north of La Salle, rather than a line of its own into Chicago. Boston money associated with the Michigan Central, the Forbes group, came in. The connection was Mendota. The 45.61 miles from Aurora were finished on October 20, 1853, and met the Illinois Central.
Three neighbors then filled out the Illinois X. The Central Military Tract, chartered February 15, 1851, opened between Mendota and Galesburg on December 7, 1854, and merged with the Burlington on July 9, 1856. The Peoria & Oquawka, incorporated February 12, 1849, opened from Galesburg to East Burlington on March 17, 1855, was renamed the Peoria & Burlington, and merged on June 24, 1864. The Northern Cross that matters here was chartered February 10, 1849, from the remnants of an 1837 company of the same name. Most of that older company became the Wabash. This Northern Cross opened between Quincy and Galesburg on January 31, 1856, was renamed the Quincy & Chicago, and joined the Burlington on April 28, 1864.

On February 14, 1855 the legislature authorized the Chicago & Aurora to take the name Chicago, Burlington & Quincy. The railroad then built its own line from Aurora into Chicago, so it could drop the Galena trackage rights. That line opened on December 26, 1865. The Illinois map was an X: Chicago to Galesburg, and from Galesburg west to Burlington, southwest to Quincy, and southeast to Peoria. In 1964 the railroad painted 5632 gold for its own centennial of the Chicago line.
John Murray Forbes and John L. Gardner carried the expansion. The Hannibal & St. Joseph, chartered February 16, 1847, and in the Forbes group from 1854, opened across Missouri on February 15, 1859. A fourteen-mile Quincy & Palmyra connected it to the river, and a Mississippi bridge at Quincy opened on November 9, 1868. The Kansas City, St. Joseph & Council Bluffs, formed in 1870 from earlier companies, had through service among its three namesake cities from November 25, 1869.
The Burlington & Missouri River was chartered May 12, 1869, to build from Burlington to Council Bluffs and the Union Pacific. By lease it reached Council Bluffs on January 3, 1870, using the St. Joseph & Council Bluffs from Pacific Junction. A direct Omaha connection, the Omaha & South Western, opened July 19, 1871. The Burlington leased the Burlington & Missouri River on December 31, 1872.

The Burlington reached Denver on May 29, 1882, and a direct Twin Cities line on August 23, 1886. A St. Louis corridor opened on March 4, 1894. The same year, on October 28, the railroad met the Northern Pacific at Huntley, Montana. Forbes died on October 12, 1898, and Gardner on December 10. By then the modern map was largely in place.
James J. Hill added the Northern Pacific to the Great Northern in 1899 and the Burlington on May 21, 1901. Great Northern and Northern Pacific each took nearly half the stock, which gave the northern transcontinentals their Chicago connection. Hill then built the Spokane, Portland & Seattle as the bridge from Spokane to Portland. A 1927 plan to merge the northern lines and lease the Burlington failed when the Interstate Commerce Commission would approve it only without the Burlington. The owners kept the Q. The merger that Hill wanted waited until 1970.

The largest addition was the Colorado & Southern, taken in on December 19, 1908. The C&S itself dated from December 19, 1898, when it gathered the bankrupt Union Pacific, Denver & Gulf, from Orin Junction, Wyoming, through Cheyenne, Denver, and Pueblo to the Texas and New Mexico line. The property included the narrow-gauge branches southwest of Denver, the Colorado Central and the Denver, South Park & Pacific, into Gunnison, Leadville, Como, and Georgetown. Until 1918 the Colorado Midland was operated jointly with the Rio Grande.
The Fort Worth & Denver City met the Colorado & Southern at Texline and ran to Fort Worth. On June 1, 1925 it took Rock Island trackage rights into Dallas. In 1905 the Colorado & Southern, jointly with the Rock Island, took the Trinity & Brazos Valley, from Cleburne toward Mexia and, in 1907, Houston, with a branch from Teague to Waxahachie. Galveston was reached by trackage rights on the Texas & New Orleans. The Trinity & Brazos Valley failed in 1914 and was reorganized as the Burlington-Rock Island on July 7, 1930, still owned by the two parents. The Cleburne–Mexia segment, which had used the Santa Fe into Fort Worth, was abandoned in the 1930s. On June 1, 1931 the Dallas–Waxahachie rights moved from the Texas & New Orleans to the Katy.

North of the subsidiaries, a line from Orin Junction to the Burlington’s Montana track at Fromberg opened on October 18, 1914. In 1952 the parent railroad was 8,806 miles. The Colorado & Southern was 748 and the Fort Worth & Denver 1,364. Those are three figures. The map above is the combined network.

Among grangers the Burlington was unusual. Agriculture was there, on a thick map of branches, and so were southern Illinois coal, manufactures, and a set of interchange gates. The worst year was 1932, the year Ralph Budd became president. He treated the railroad as something that had to be redesigned for highways and airlines. Centralized traffic control was in use as early as 1927. Budd retired in 1949. Harry C. Murphy followed him.

Union Pacific’s M-10000 of February 25, 1934, was the first of the lightweight trainsets. The Burlington’s was the one that lasted. The order went to the Budd Company on June 17, 1933: a three-car stainless train, railway post office, baggage-coach, and coach-parlor observation, with a Winton diesel of 600 horsepower through Electro-Motive. The train was completed on April 9, 1934, and christened at Broad Street Station in Philadelphia on April 18. On May 26, 1934, the Dawn-to-Dusk dash ran from Denver to Chicago, 1,015.4 miles in 13 hours 5 minutes, at an average a shade under 78 miles an hour, with a peak of 112.5. Revenue service began November 11, 1934, as trains 21 and 20, Kansas City–Omaha–Lincoln. The railroad later named 9900 the Pioneer Zephyr so the original would not disappear into a fleet of Zephyrs. It was retired on March 20, 1960, and given to Chicago’s Museum of Science and Industry.

The Twin Cities Zephyr, the Mark Twain Zephyr, the Denver Zephyr, and the Ozark State Zephyr followed. The train people came to know best was the California Zephyr, with the Rio Grande and the Western Pacific, from 1949 until 1970. The Rio Grande kept its own segment as the Rio Grande Zephyr after the through train ended. The Burlington also forwarded the northern transcontinentals: the Empire Builder, the Western Star, the Mainstreeter, and the North Coast Limited.

The Burlington’s own shops built a large share of the roster. West Burlington, Aurora, and Havelock turned out Prairies, switchers, Hudsons, and 4-8-4s, and Baldwin supplied the Mikados and the Pacifics. George H. Drury’s list of locomotives built or rebuilt since 1900 is the steam roster. A rebuild is the same frame. The post-1900 Prairies, classes R-1 through R-5, come to 429. The Mikados come to 383: 60 O-1, 148 O-1A, 100 O-2, 60 O-3, and 15 O-4. Baldwin’s first O-1s, in 1910, kept the 64-inch drivers and, at 49,500 pounds of tractive effort, outpulled the newest 2-6-2s by about 40 percent.
Consolidations were a smaller group, for slow freight west of the Mississippi. The 2-10-2s and the eighteen M-4 2-10-4s worked southern Illinois coal, and some of them went to the Colorado & Southern. Articulateds were few. The 2-6-6-2s stayed in the Black Hills, and the single 2-8-8-2 worked the Galesburg hump.
Passenger power ran from Atlantics and Pacifics to the Hudsons and the 4-8-4s, and the last two looked alike. Baldwin delivered S-4 3000–3011 in 1930. West Burlington built 3012, rebuilt 3002 into the shrouded Aeolus, and in 1938 built 4001, the second Aeolus, without the shroud. 4000 is 3002. The 4-8-4s were eight Baldwin O-5s and twenty-eight shop-built O-5As. Oil-burning engines were class O-5B, including 5632, the gold engine at the top of this page. Commercial steam ended in January 1959. After 1960 the excursion engines were 4960 and 5632. 4960’s last Burlington trip was the Denrock Zephyr on July 17, 1966. The class grid, from the switchers through the 4-8-4s, is the steam roster.
Freight dieselization began with the FT sets of 1944. The last new road freight units lettered for the Burlington were SD45s and U23Cs in 1969. The diesel roster counts each frame once. The parent list is 951 locomotives. Colorado & Southern and Fort Worth & Denver are their own lists, 72 and 36 new frames through the merger. A unit transferred from the parent is the same locomotive and is not counted again. Nine small industrial locomotives never joined that count: Plymouth 1 and 2, Mack 100, Whitcomb 101, Porter 111, Whitcomb 112, and Midwest 65-ton 9121–9123.

Murphy rebuilt Clyde Yard, in Cicero, as a hump, carried centralized traffic control out to 1,750 miles of main line, and bought the Vista-Domes for the first-class trains. The Centennial Cutoff opened on October 28, 1952, and shortened Chicago–Kansas City by 22 miles. The northern merger was filed, fought, and filed again. The Interstate Commerce Commission approved it on November 30, 1967. The four railroads became the Burlington Northern at 12:01 a.m. on March 2, 1970. John M. Budd of the Great Northern was the first chairman. Louis W. Menk, who had come from the Burlington, was the first president. William J. Quinn was the Burlington’s president at the merger.
The Colorado & Southern and the Fort Worth & Denver were not dissolved that morning. They came into the Burlington Northern as subsidiaries. The Colorado & Southern was absorbed at the end of 1981. The Burlington Northern and the Atchison, Topeka & Santa Fe merged on September 22, 1995. The Chicago–Aurora main line, the Denver road, and the Texas line are still BNSF routes. Chicago commuter trains on the Burlington became Metra.
