The Chicago, Burlington and Quincy Railroad (reporting mark CBQ) was a railroad that operated in the Midwestern United States. Commonly referred to as the Burlington Route, the Burlington, or as the Q, it operated extensive trackage in the states of Colorado, Illinois, Iowa, Missouri, Nebraska, Wisconsin, Wyoming, and also in Texas through subsidiaries Colorado and Southern Railway, Fort Worth and Denver Railway, and Burlington-Rock Island Railroad. Its primary connections included Chicago, Minneapolis–Saint Paul, St. Louis, Kansas City, and Denver. Because of this extensive trackage in the midwest and mountain states, the railroad used the advertising slogans "Everywhere West", "Way of the Zephyrs", and "The Way West".
In 1967, it reported 19,565 million net ton-miles of revenue freight and 723 million passenger miles; corresponding totals for C&S were 1,100 and 10 and for FW&D were 1,466 and 13. At the end of the year, CB&Q operated 8,538 route-miles, C&S operated 708, and FW&D operated 1,362 (these totals may or may not include the former Burlington-Rock Island Railroad). In 1970, it merged with the Northern Pacific Railway and the Great Northern Railway to form the Burlington Northern Railroad.
The earliest predecessor of the Chicago, Burlington and Quincy, the Aurora Branch Railroad, was chartered by act of the Illinois General Assembly on October 2, 1848. The charter was obtained by citizens of Aurora and Batavia, Illinois, who were concerned that the Galena and Chicago Union Railroad would bypass their towns in favor of West Chicago on its route; at the time, that was the only line running west from Chicago. The Aurora Branch was built from Aurora, through Batavia, to Turner Junction in what is now West Chicago. The line was built with old strap rail and minimal, if any, grading. Using a leased locomotive and cars, the Aurora Branch ran passenger and freight trains from Aurora to Chicago via its own line from Aurora to Turner Junction and one of the G&CU's two tracks east from there to Chicago. The G&CU required the Aurora Branch to turn over 70 percent of their revenue per ton-mile handled on that railroad; as a result, in the mid-1850s, surveys were ordered to determine the best route for a railroad line to Chicago.
The line from Aurora to Chicago was built through the fledgling towns of Naperville, Lisle, Downers Grove, Hinsdale, Berwyn, and the west side of Chicago. It was opened in 1864, and passenger and freight service began. Regular commuter train service started in 1864 and remains operational to this day, making it the oldest surviving regular passenger service in Chicago. Both the original Chicago line, and to a much lesser extent, the old Aurora Branch right of way, are still in regular use today by the Burlington's present successor BNSF Railway.
The company was renamed Chicago and Aurora Railroad on June 22, 1852, and given expanded powers to extend from Aurora to a point north of LaSalle; this extension, to Mendota, was completed on October 20, 1853. Another amendment, passed February 28, 1854, authorized the company to build east from Aurora to Chicago via Naperville, and changed its name to Chicago and Southwestern Railroad. The latter provision was never acted upon, and was repealed by an act of February 14, 1855, which instead reorganized the line as the Chicago, Burlington and Quincy Railroad. With a steady acquisition of locomotives, cars, equipment, and trackage, the Burlington Route was able to enter the trade markets in 1862. From that year to date, the railroad and its successors have paid dividends continuously, and never run into debt or defaulted on a loan—the only Class I U.S. railroad for which this is true.
After extensive trackwork was planned, the Aurora Branch changed its name to the Chicago and Aurora Railroad in June 1852, and to Chicago, Burlington, and Quincy Railroad in 1856, and shortly reached its two other namesake cities, Burlington, Iowa, and Quincy, Illinois. In 1868 CB&Q completed bridges over the Mississippi River at both Burlington and Quincy, giving the railroad through connections with the Burlington and Missouri River Railroad (B&MR) in Iowa and the Hannibal & St. Joseph Railroad (H&StJ) in Missouri. In 1860 the H&SJ carried the mail to the Pony Express upon reaching the Missouri River at St. Joseph, Missouri. In 1862 The first Railway Post Office was inaugurated on the H&StJ to sort mail on the trains way across Missouri.
The B&MR continued building west into Nebraska as a separate company, the Burlington & Missouri River Rail Road, founded in 1869. During the summer of 1870 it reached Lincoln, the newly designated capital of Nebraska and by 1872 it reached Kearney, Nebraska. That same year the B&MR across Iowa was absorbed by the CB&Q. By the time the Missouri River bridge at Plattsmouth, Nebraska, was completed the B&MR in Nebraska was well on its way to Denver. That same year, the Nebraska B&MR was purchased by the CB&Q, which completed the line to Denver by 1882.[page needed]
Burlington's rapid expansion after the American Civil War was based upon sound financial management, dominated by John Murray Forbes of Boston and assisted by Charles Elliott Perkins. Perkins was a powerful administrator who eventually forged a system out of previously loosely held affiliates, virtually tripling Burlington's size during his presidency from 1881 to 1901.
Ultimately, Perkins believed the Burlington Railroad must be included into a powerful transcontinental system. Though the railroad stretched as far west as Denver and Billings, Montana, it had failed to reach the Pacific Coast during the 1880s and 1890s, when construction was less expensive. Though approached by E. H. Harriman of the Union Pacific Railroad, Perkins felt his railroad was a more natural fit with James J. Hill's Great Northern Railway. With its river line to the Twin Cities, the Burlington Route formed a natural connection between Hill's home town (and headquarters) of St. Paul, Minnesota, and the railroad hub of Chicago. Moreover, Hill was willing to meet Perkins' $200-a-share asking price for the Burlington's stock. By 1900, Hill's Great Northern, in conjunction with the Northern Pacific Railway, held nearly 100 percent of Burlington's stock.
By 1899, the company had rostered 1,205 locomotives, 936 passenger cars and 40,720 freight cars.
In 1901, a rebuffed Harriman tried to gain an indirect influence over the Burlington by launching a stock raid on the Northern Pacific. Though Hill managed to fend off this attack on his nascent system, it led to the creation of the Northern Securities Company, and later, the Northern Securities Co. v. United States ruling by the U.S. Supreme Court.
Burlington strike of 1888
The only major strike in the line's history came in 1888, the Burlington railway strike of 1888. Unlike most strikes, which were based on unskilled workers, this one was based on the highly skilled well-paid engineers and firemen, a challenge to management prerogatives. A settlement would have been much cheaper, but President Perkins was determined to assert ownership rights and destroy the union threat. The fight dragged on 10 months before the financially and emotionally exhausted strikers finally gave up, and Perkins declared a total victory. However, he had spent heavily on strikebreakers, lawsuits, and police protection, hurting the balance sheets and putting the railroad in a poor position to face the nationwide depression of the Panic of 1893.[page needed]
Following the purchase of the Burlington by GN and NP, expansion continued. In 1908, the CB&Q purchased both the Colorado & Southern and Fort Worth & Denver Railways, giving it access south to Dallas and the Gulf of Mexico ports in Houston and Galveston. It also extended its reach south in the Mississippi Valley region by opening up a new line from Concord, Illinois, south to Paducah, Kentucky. It was during this period that the Burlington was at its largest, exceeding just over 12,000 route miles in 14 states by the 1920s. With the First World War having the same effect on the railroad as on all other railroads, during the 1920s, the Burlington Route had an increasingly heavy amount of equipment flooding the yards. With the advent of the Great Depression, the CB&Q held a good portion of this for scrap.
In 1929, the CB&Q created a subsidiary, the Burlington Transportation Company, to operate intercity buses in tandem with its railway network. On January 1, 1932, the CB&Q received a new president; former Great Northern Railroad president Ralph Budd. By which time, the CB&Q was facing a decline in passenger ridership from the Depression, and U.S. President Franklin D. Roosevelt was exploring ways to help the rail industry improve. Ralph Budd subsequently asked for a streamlined stainless-steel train to be built, and this resulted in the railroad introducing the famous Zephyrs. As early as 1897, the railroad invested in alternatives to steam power, namely, internal-combustion engines. The railroad's shops in Aurora had built a three-horsepower distillate motor in that year, but it was not reliable (requiring a massive 6,000-pound flywheel), and it had issues with overheating (even with the best metals of the day, its cylinder heads and liners would warp and melt in a matter of minutes), so it was therefore deemed impractical. Diesel engines of that era were obese, stationary monsters and were best suited for low-speed, continuous operation.
It was not reliable for a railroad locomotive; there was no diesel engine suitable for that purpose then. Always innovating, the railroad purchased "doodlebug" gas-electric combine cars from Electro-Motive Corporation (EMC) and built their own, sending them out to do the jobs of a steam locomotive and a single car. After the positive results the doodlebug cars created, and after having purchased and used three General Electric steeple-cab switchers powered by distillate engines, Ralph Budd requested the Winton Engine Company to design and construct a light, powerful diesel engine that could stand the rigors of continuous, unattended daily service.
The experiences of developing these engines can be summed up shortly by General Motors Research vice-president Charles Kettering: "I do not recall any trouble with the dip stick." Ralph Budd, accused of gambling on diesel power, chirped that "I knew that the GM people were going to see the program through to the very end. Actually, I wasn't taking a gamble at all." The manifestation of this gamble was the eight-cylinder Winton 8-201A engine that powered the Burlington Zephyr (built 1934) on its record-breaking run, and it opened the door for developing the long line of diesel engines that has powered Electro-Motive locomotives for the next seventy years. In 1936, the CB&Q would become one of the founding members of the Trailways Transportation System, and still provides intercity service to this day as Burlington Trailways.
1940 was the final year the CB&Q added steam locomotives to their roster, having completed construction on their O-5A class locomotives at the West Burlington, Iowa shops. With their freight traffic weighing 31 million tons that year, the CB&Q saw no further necessity for any more steam or diesel locomotives to be added to their roster. In 1942, following the United States' entrance into World War II, the railroad's freight traffic increased to 49 million tons, with Ralph Budd (now named President Roosevelt's federal transportation commissioner) poised to ensure his company would help the war effort. In 1943, the War Production Board authorized EMC (now reincorporated as EMD) to construct sixteen FT locomotives for delivery to the CB&Q the following year, by which time, the road's freight traffic peaked 57 million tons.
After World War II ended, the CB&Q began ordering additional diesel locomotives from EMD, as part of a $140-million program to dieselize their roster. August 31, 1949, was Ralph Budd's final day as president of the railroad before he would retire during that year's Chicago Railroad Fair, and Harry C. Murphy succeeded him in September. Dieselization of the CB&Q's commercial passenger operations was completed on September 26, 1952, when the last of the 4-6-2 locomotives that operated for the Chicago-Aurora suburban service were retired; the remaining steam locomotives on the CB&Q were primarily reassigned as freight haulers and yard switchers. The first division on the CB&Q to be fully dieselized was the Casper Division in Wyoming, where EMD GP7 road switchers were delivered in 1951.
In 1955, regular performance on class 3 overhauls on steam locomotives were discontinued, and Harry C. Murphy opted for the railroad's remaining steam fleet to use up their previously-restored mileage throughout the next year. By which time, the majority of the Burlington's steam fleet were relegated to operate east of Lincoln, Nebraska, with only two steam locomotives held for back-up service west of Lincoln. The final division on the CB&Q to be fully dieselized was the Beardstown Division in Southern Illinois, where 2-8-2 locomotive No. 4997 worked the last commercial steam assignment for the railroad at Herrin Junction on January 27, 1959 (the only major U.S. railroads to operate revenue steam after this date were Union Pacific, Illinois Central, Nickel Plate Road, Norfolk and Western, Grand Trunk Western, Duluth, Missabe and Iron Range, and Lake Superior and Ishpeming). CB&Q subsidiary Colorado and Southern eventually ended their commercial steam operations on October 11, 1962, when 2-8-0 No. 641 pulled a final freight train on the Leadville-Climax branch in Colorado.
On July 1, 1965, Harry Murphy retired from his position as president of the CB&Q (he remained on the railroad as a director until October), and former Frisco Railway president Louis W. Menk took over as president and CEO. During his presidency, Louis Menk explored ways to reduce costs for the CB&Q's passenger operations and to reshape the road's freight operations. Passenger service was markedly reduced, as people had shifted to using private automobiles for transportation. In late 1966, Louis Menk became president of the Northern Pacific, leaving William John Quinn in charge of the CB&Q.
As the financial situation of American railroading continued to decline throughout the 1960s, forcing restructuring across the country, the CB&Q merged with the Great Northern, Northern Pacific, and the Spokane, Portland and Seattle (SP&S) railroads on March 2, 1970, to form the Burlington Northern Railroad (BN), with Louis Menk serving as the company's first president and CEO (twenty-six years later, the BN and Santa Fe Railroads merged to become the Burlington Northern and Santa Fe Railway (BNSF)). Most passenger operations would be assumed in 1971 by Amtrak.
Beginning in the summer of 1955, the CB&Q hosted a series of occasional steam excursion trains per request of railfan clubs, such as the Illinois Railroad Club. Harry C. Murphy was a steam fan who recognized the popularity in steam locomotives, and he authorized additional steam excursion trains to take place on the railroad throughout the late 1950s and early 1960s. Twenty-one steam locomotives of varying classes took part in the CB&Q's new steam excursion program, only two of which remained operational by 1961: 2-8-2 No. 4960 and 4-8-4 No. 5632. In 1962, the CB&Q's passenger department began sponsoring the excursion runs by offering ticket discounts to paying customers, and the Burlington began to host several school trains for school students.
In 1964, steam excursion operations on the railroad had dwindled, in the wake of rising operation and maintenance costs and a loss of experienced steam locomotive mechanics; the only factors that kept the CB&Q's steam program going were public demand and Harry Murphy's passion for steam. In the process of reducing operating costs for the railroad, Harry Murphy's successor, Louis Menk, ordered for the CB&Q's steam excursion program to be shut down by August 1, 1966. Despite a subsequent public outcry and protest over the program's cancellation, the No. 4960 locomotive pulled the railroad's final excursion train on July 17.
The Burlington Zephyrs
The railroad operated a number of streamlined passenger trains known as the Zephyrs which were one of the most famous and largest fleets of streamliners in the United States. The Burlington Zephyr, the first American diesel-electric powered streamlined passenger train, made its noted "dawn-to-dusk" run from Denver, Colorado, to Chicago, Illinois, on May 26, 1934. On November 11, 1934, the train was put into regularly scheduled service between Lincoln, Nebraska, and Kansas City, Missouri. Although the distinctive, articulated stainless steel trains were well known, and the railroad adopted the "Way of the Zephyrs" advertising slogan, they did not attract passengers back to the rails en masse, and the last one was retired from revenue service with the advent of Amtrak.[page needed]

The Burlington was a leader in innovation; among its firsts were use of the printing telegraph (1910), train radio communications (1915), streamlined passenger diesel power (1934) and vista-dome coaches (1945). In 1927, the railroad was one of the first to use Centralized Traffic Control (CTC) and by the end of 1957 had equipped 1,500 miles (2,400 km) of its line. It played a central role in bringing air brakes to freight service.
The railroad had one of the first hump classification yards at its Cicero Avenue Yard in Chicago, allowing an operator in a tower to line switches remotely and allowing around-the-clock classification. The company also tested the twin cylinder car.
