Chicago, Burlington & Quincy: "Everywhere West"

logoad1.jpg

Last revised: January 16, 2024

By: Adam Burns

Some railroads were seemingly destined to become strong, profitable operations.  The Chicago, Burlington and Quincy was one such example.  Its history traces back to the pre-Civil War period when trains near or west of the Mississippi River remained a relative novelty.  

During the mid-19th century the "Q's" earliest predecessor had established through service to Chicago and then spent the next several decades rapidly expanding.  Its slogan, "Everywhere West," was quite befitting for this classic Midwestern granger.  

While the CB&Q did operate many secondary, agricultural branches it also boasted important through corridors to the Twin Cities, Denver, Kansas City, Omaha, southern Montana, and even reached the Gulf Coast!  The Burlington was also quite close with the communities it served and highly visible in the public eye.  

It maintained an impressive fleet of high-class trains in addition to hosting its allying roads' transcontinental services.  

The long sought merger with the Great Northern, Northern Pacific, and the Spokane, Portland & Seattle, finally became a reality in early 1970 forming the gigantic Burlington Northern system.  Today, all of the Burlington's principal lines remain in operation under successor BNSF Railway.

History

The complete corporate history of the Burlington could encompass many books and the railroad has already been covered extensively over the years, including its narrow-gauge network in central Colorado.  Presented here will be only a brief synopsis.  

During the road's height it spanned the Midwest and thanks to acquisitions like the Colorado & Southern and Fort Worth & Denver also reached Texas, New Mexico, Wyoming, and Colorado.  Its legend lives on today through its Zephyr name and Chicago main line which continues to see hundreds of freight and commuter trains daily.

If you can find a copy the most thorough title available on the CB&Q is Richard Overton's, "Burlington Route: A History Of The Burlington Lines." The book was originally published in 1965 to celebrate the railroad's centennial and is currently out-of-print but copies can be found floating around from time to time and occasionally appear on Amazon.com.  

The Burlington's heritage is quite fascinating, owing its start to a predecessor of future rival Chicago & North Western, the Galena & Chicago Union (G&CU).  By the early 1850's railroad fever had spread across the Midwest as promoters clamored to reach the growing metropolis of Chicago, the future railroad capital of America.

Predecessors

The G&CU was chartered in 1836 and had opened from Chicago to Elgin by January of 1850.  It then extended to Freeport during September of 1853.  Like so many communities of that era, the town of Aurora, Illinois yearned for its own railroad.  In particular, they were growing increasingly concerned about the G&CU.  

The neighboring towns it served would potentially render theirs obsolete.  Since the 1820's railroads were proving themselves as the revolutionary vehicle for a prosperous economic future, able to move freight and people at unprecedented speeds.

Aurora secured chartering rights through the Illinois state legislature for the Aurora Branch Railroad (ABRR) on February 12, 1849.  On February 22nd the company was formally organized.  This little system was the Chicago, Burlington & Quincy's genesis.  

It was intended to run north out of Aurora, along the Fox River, reach Batavia and then turn slightly northeastward to Turner Junction (now West Chicago) where an interchange would be established with the G&CU for direct service into Chicago.  

In those days, such fledgling operations had extreme difficulty in just getting started, particularly in the case of a local system like the Aurora Branch.  Without strong financial backing the ABRR was forced to rely on its directors going door-to-door to sell stock subscriptions individually.

Such tactics usually have mixed results but the group was successful enough that actual construction began within a year. By the spring of 1850 grading was underway as crews worked their way south from Turner Junction and on August 22nd tracks had reached Batavia.  

In a most interesting historical footnote the Aurora Branch held special festivities on September 2nd to inaugurate rail service.  However, without any actual equipment of its own the company had to borrow a locomotive and coach from the G&CU.  

The locomotive was none other than the 4-2-0 named Pioneer, the very same iron horse which had been honored as the first ever to operate out of Chicago on October 24, 1848.  As rails of the Aurora Branch pushed southward the line was completed into Batavia on October 4th and only a few weeks later, on October 21st, the railroad launched regular service over the G&CU into Chicago.  

Its promoters were onto something as the small pike proved a financial success.  However, with elements of future rivals either underway or in the planning stages there was little time to celebrate.

Expansion

With an eye towards expansion the company was renamed as the Chicago & Aurora Railroad on June 22, 1852.  Ironically, its original intention here was not to build east to Chicago but rather west towards, "a point 15 miles north of La Salle...to connect with any railroad to built northward from that town."  

At the same time much more prominent financial backing arrived from eastern sources, notably those financing the Michigan Central (the "Forbes Group"), who became interested in the C&A project.

The "point 15 miles north of La Salle" was Mendota and the 45.61 miles to this town, which established a connection with the expanding Illinois Central, was officially completed on October 20, 1853.  In short order the former Aurora Branch was fast becoming one of the Midwest's prominent systems.

Its successor was later merged with the Northern Cross Railroad (This company had been chartered on February 10, 1849 from the remnants of another carrier by same name established in 1837.  Most of this failed predecessor eventually became the Wabash except for a stretch of grading completed north of Quincy.), Central Military Tract Railroad (chartered on February 15, 1851), and Peoria & Oquawka (incorporated on February 12, 1849).

Formation

The 1850's were a whirlwind decade that witnessed a great deal of expansion and the official creation of the Chicago, Burlington & Quincy Railroad.  On February 14, 1855 the state legislature authorized the C&A to adopt this new name and what followed included the railroads previously mentioned joining it.  

On December 7, 1854 the Central Military Tract began operation between Mendota and Galesburg, then merged with the CB&Q on July 9, 1856.  The Peoria & Oquawka was completed between Galesburg and East Burlington on March 17, 1855 which was subsequently followed by the Northern Cross opening between Quincy and Galesburg on January 31, 1856.  

The former was renamed as the Peoria & Burlington Rail Road before merging with the CB&Q on June 24, 1864; the latter was also renamed, as the Quincy & Chicago, and had joined a few months earlier on April 28th.  That year also witnessed the Burlington constructing its own route into Chicago to obviate the need of G&CU trackage rights.  

The line officially opened on December 26, 1865 and gave the CB&Q a network shaped roughly like an "X" extending from Chicago to Galesburg before splitting west to Burlington, southwest to Quincy, and southeast to Peoria.

Modern Network

These roads constituted the original core of the Burlington system.  However, like every other major Midwestern granger many more predecessors went in to creating the modern CB&Q network.  Two other notables included the Hannibal & St. Joseph Railroad (chartered on February 16, 1847) and the Burlington & Missouri River Rail Road.

The former, acquired by the Forbes Group in 1854, was the first to complete an east-west route across Missouri, opening on February 15, 1859.  The railroad connected its namesake cities and interchanged with another Forbes road, the Quincy & Palmyra, at Palmyra.  

This system was only 14 miles but provided a connection to the CB&Q at Quincy once a bridge had opened over the Mississippi River on November 9, 1868.  Finally, there was the Kansas City, St. Joseph & Council Bluffs, an 1870 formation of various systems which had opened service between all three of its namesake cities on November 25, 1869.

 This had offered a direct, if somewhat roundabout, link to Council Bluffs.  Following the H&StJ's completion the B&MR was chartered on May 12, 1869 to build another lengthy route, this time from Burlington directly across the state to Council Bluffs/Omaha at the eastern point of the recently completed Transcontinental Railroad (Union Pacific).  

Work on the road proceeded quickly and, via lease, had reached Council Bluffs on January 3, 1870 by way of the St. Joseph & Council Bluffs Rail Road from Pacific Junction.  A direct link into Omaha was established by July 19, 1871 (Omaha & South Western Railroad).  The CB&Q took lease of the B&MR on December 31, 1872.

With a route already established to Kansas City the Burlington was fast becoming one of the Midwest's preeminent carriers. The two men most instrumental behind its great expansion was John Murray Forbes and John L. Gardner.  Forbes died on October 12, 1898, followed by Gardner on December 10th.  

However, before their passing most of the modern CB&Q had been put into place. On May 29, 1882 the "Q" reached Denver, Colorado and then four years later finally had a coveted direct route into the Twin Cities, completed on August 23, 1886.  

There was additional growth during the 1890's as a new corridor opened to St. Louis on March 4, 1894.  The railroad pushed further west into Montana, completing a connection with the Northern Pacific at Huntley on October 28th that same year.  

The transcontinental NP became more than just an interchange partner; the great "Empire Builder," James J. Hill, who was instrumental in finishing the Great Northern added the Northern Pacific to his portfolio in 1899, followed by the Burlington on May 21, 1901.  Shortly thereafter he also established the Spokane, Portland & Seattle as a bridge road linking Spokane, Washington with Portland, Oregon.

Even into the 20th century the Burlington's expansion was not over.  Its biggest acquisition came on December 19, 1908 via the Colorado & Southern Railway.  

The C&S had been created on December 19, 1898 to take over the bankrupt Union Pacific, Denver & Gulf Railway stretching from Orin Junction, Wyoming to the Texas/New Mexico border via Cheyenne, Denver, and Pueblo.  

The property, a former Union Pacific subsidiary, also included a segment of narrow-gauge trackage stretching southwest of Denver which reached the mining towns of Gunnison, Leadville, Como, Georgetown, and others.

Chicago, Burlington & Quincy 4-6-0 #637 (Class K-2) is seen here on September 2, 1956 hosting the Illini Railroad Club's "Triangle" fan trip. This excursion ran along the main line from Chicago Union Station-Aurora then south to Streator, Illinois; back to the main line at Zearing, Illinois, and finally back to Aurora/Chicago. The little Ten-Wheeler, with GP7 #235 assisting, handled the loop from Aurora-Streator-Zearing-Aurora while 4-6-4 #4000 powered the run between Aurora-Chicago. The Ten-Wheeler was manufactured by the Rogers Locomotive & Machine Works in November, 1892 and today is on display at the Illinois Railway Museum. American-Rails.com collection.

These fabled lines were operated by the Colorado Central and most notable of all the Denver, South Park & Pacific (until 1918 it also included the Colorado Midland Railway, operated jointly with the Rio Grande).  Finally, there was the Fort Worth & Denver City, which fell under C&S control.  

At Texline, Texas the FW&DC connected with the C&S end-of-track and offered through service to Fort Worth.  On June 1, 1925 it acquired trackage rights over Rock Island's Chicago, Rock Island & Gulf to reach Dallas.  

System Map (1969)

Beyond Dallas/Fort Worth the C&S took over the Trinity & Brazos Valley Railway (T&BV) in 1905.  It was jointly owned with the Rock Island and originally extended from Cleburne to Mexia before expanding to Houston in 1907, which also included a branch from Teague to Waxahachie.  

To reach nearby Galveston the road established trackage rights over the Texas & New Orleans (Southern Pacific).  Chronic financial problems forced the T&BV into bankruptcy during 1914 and it was reorganized as the Burlington-Rock Island Railroad on July 7, 1930 with the two parent roads remaining in control.  

The Cleburne-Mexia segment, which utilized trackage rights over the Gulf, Colorado & Santa Fe (Santa Fe) to reach Fort Worth was abandoned during the 1930's.  This followed another change in the trackage rights agreement between Dallas and Waxahachie as the B-RI switched from the T&NO to the Missouri-Kansas-Texas (Katy) on June 1, 1931.  

Beyond the great Lone Star State few other major expansions occurred (one notable addition was a new extension connecting the C&S at Orin Junction with the CB&Q's original trackage into Montana at Fromberg, which opened on October 18, 1914).  The modern Chicago, Burlington & Quincy was a powerful system operating 11,000 route miles from the Midwest to the Rocky Mountains and Gulf Coast.

Peak Years

The Burlington had long been a prosperous carrier throughout the 19th century and this continued into the 20th.  The finely managed company was one of the few to never experience a bankruptcy throughout its corporate history.  By the 1920's it was somewhat unique as a granger in that it did rely greatly on agriculture.  

Instead, its freight was diversified and included everything from coal (tapped from the Ohio River valley in southern Illinois) to manufactured goods.  There was also various less-than-carload movements and several interchange gateways.  

Following the Great Depression of 1929 and the downtrodden economy of the 1930's the Burlington struggled but avoided bankruptcy.  

According to Mike Schafer's book, "Classic American Railroads," its worst year ever was 1932, the same year that Ralph Budd became president.  Arguably the road's most influential leader he turned the company into an even greater machine of efficiency.

Budd, unlike most railroaders, did not hold onto outdated operational practices.  This issue, the lack of modernity and innovation, plagued the industry long after World War II.  

He realized as early as the 1930s that railroads would continually need to find better ways of retaining and sustaining business if they were to survive in the modern age of highways and airliners.

The most publicly visible aspect of this was the Zephyr streamliner.  Rival Union Pacific beat it to the punch by acquiring the first-ever such trainset on February 25, 1934 known as the M-10000.  However, it was the Burlington's version which ultimately proved the most successful.  

As Mike Schafer and Joe Welsh note in their book, "Streamliners: History Of A Railroad Icon," the railroad placed its order with the Budd Company on June 17, 1933 for a sleek, stainless-steel trainset which was 197-feet long and featured three cars (Railway Post Office, baggage-coach, and coach-parlor observation).  

Received on April 7, 1934 it was the first of its kind to utilize a diesel engine; a 660 horsepower prime mover from the Winton Engine Company (a subsidiary of General Motors/Electro-Motive).  The diesel proved much more reliable than the M-10000's gasoline-distillate prime mover. 

The Zephyr #9900 (or Pioneer Zephyr) wowed the public with its sleek appearance and blazing fast speeds.  During its legendary trial run held on May 26th the trainset left Denver at 5:05 AM in anticipation of reaching Chicago that same day.  With an average speed of 78 mph it completed the 1,015-mile trip in just 14 hours, arriving in the Windy City at 7:10 PM later that evening.

Not surprisingly, this accomplishment and the train's good looks made it an instant publicity success and the Burlington went on to order several trainsets.  Eventually, an entire fleet graced its rails with names like the Twin Cities ZephyrMark Twain ZephyrDenver Zephyr, and Ozark State Zephyr.  

Perhaps the railroad’s most famous was the California Zephyr, jointly run with the Rio Grande and Western Pacific. The train, launched in 1949, traveled through some of the most spectacular scenery in the country.  Thanks to the train's top notch service it witnessed strong ridership through the 1960's.  

As the financial fortunes of Western Pacific waned the train was discontinued in 1970 while the Rio Grande operated its segment as the Rio Grande Zephyr for several years following. While Budd retired from the CB&Q in 1949 his legacy carried on for many years.

Always looking to cut costs and improve service he launched the transition from steam to diesel and implemented Centralized Traffic Control (CTC) as early as 1927.

- Steam was gone from main line service by the late 1950's although the C&S maintained a single locomotive in service into 1962.  In addition, fan trips were maintained through President Harry Murphy, Budd's successor, until his retirement in 1965 when these were discontinued the following year. -

Burlington Northern Merger

Murphy continued the improvements by updating the road's big classification yard in Chicago, Clyde Yard, into a modern hump facility, expanded CTC to protect 1,750 main line miles by the 1960's, opened the "Centennial Cutoff" on October 28, 1952 (this route shortened the distance between Chicago and Kansas City by 22 miles), and acquired the popular Vista-Domes for its top trains.  

The railroad, however, was destined to be merged with its allying roads, a dream James Hill had envisioned since the early 20th century.  

The attempt had been made numerous times until the Interstate Commerce Commission approved the deal in the late 1960's.  On March 2, 1970 Burlington Northern was born through the CB&Q, GN, NP, and SP&S.  

The BN lasted only 25 years before merging with the Atchison, Topeka & Santa Fe to become the Burlington Northern Santa Fe on September 22, 1995.  

Even though the Burlington is no more today it continues to live on as almost all of its main lines remain important routes for its successor. Forever recognized as one of the best managed railroads of all time perhaps it is best remembered for maintaining a close relationship with the communities it served.
