The fast-growing port city of Baltimore, Maryland, faced economic stagnation unless it opened a route to the Western states. On February 27, 1827, twenty-five merchants and bankers studied the best means of restoring "that portion of the Western trade which has recently been diverted from it by the introduction of steam navigation.". Their answer was to build a railroad: one of the first commercial lines in the world. Their plans worked well, despite many political problems from canal backers and other railroads. Only the

The railroad grew from a capital base of $3 million in 1827 (equivalent to $ million in ) to a large enterprise generating $2.7 million of annual profit on its of track in 1854, with 19 million passenger miles. The railroad fed tens of millions of dollars of shipments to and from Baltimore and its growing hinterland to the west, thus making the city the commercial and financial capital of the region south of Philadelphia.

The capital of the proposed company was fixed at $5 million, but the B&O was initially capitalized in 1827 with a $3 million issue of stock. Half of this stock was reserved for the Maryland state government, which invested $1,000,000, and the municipal government of Baltimore, which invested $500,000. The remaining private equity was purchased by around 22,000 people, equivanlent to one-quarter of the city's population at the time.

This line was partially funded by the state of Maryland, and was operated separately until the 1870s, with Maryland receiving a 25 percent cut of gross passenger receipts. The B&O's charter also forbade further taxation of the railroad, and that no-tax provision was upheld in the 1840s after Baltimore City tried to tax it. This Washington Branch line was built in stone, much like the original mainline. By this time, however, strap rail was no longer used for new construction. Most of the stone bridges on the Old Main Line did not last long, being washed out by the periodic flooding of the Patapsco River and replaced at first by Bollman Truss bridges. The

Early engineering

When construction began on the B&O in the 1820s, railroad engineering was in its infancy. Unsure exactly which materials would suffice, the B&O erred on the side of sturdiness and built many of its early structures of granite. Even the track bed to which the iron strap rail was affixed consisted of stone. Though the granite soon proved too unforgiving and expensive for track, most of the B&O's monumental bridges have survived to this day, and many are still in active railroad use by CSX. Baltimore's Carrollton Viaduct, named in honor of

American Civil War

At the outset of the American Civil War, Civil War, the B&O possessed 236 locomotives, 128 passenger coaches, 3,451 rail cars and of rail road, all in states south of the Mason–Dixon line, as Garrett had noted before the war began. Although many Maryland in the American Civil War, Marylanders had Southern sympathies, Garrett and Hopkins supported the Union. The B&O became crucial to the Federal government during the Civil War, being the main rail connection between Washington, D.C., and the northern states, especially west of the Appalachian mountains. However, its initial problem became Lincoln's first Secretary of War, Simon Cameron, a major stockholder in the rival North Central Railroad, which received long haul freight destined for Baltimore from the rival

. Furthermore, the Pennsylvania Railroad and other investors sought permission to construct rail lines which threatened the B&O's monopolies on the Washington Branch (between Relay and Washington DC) and westward through Cumberland, Maryland. Raids and battles during the war also cost the B&O substantial losses, many never indemnified. Master of Transportation Prescott Smith kept a diary during the war years, describing incidents such as the June 1861 derailment of a 50 car coal train, which plunged into a ravine after a bridge was destroyed (the wreckage burned for months and melted the metal coal hoppers), as well as later ironclad trains (one only disabled by an artillery shell piercing the boiler).

, which was also an important work station on the B&O's main westward line. The following day, Baltimore riot of 1861, Confederate rioters in Baltimore attempted to prevent Pennsylvania volunteers from proceeding from the North Central Railway's Bolton station to the B&O's Mount Clare station, and Maryland's governor Hicks and Baltimore Mayor George William Brown (mayor), George W. Brown ordered 3 North Central and 2 Philadelphia, Wilmington and Baltimore Railroad (PW&B) bridges destroyed to prevent further federal troop movements through (and riots in) the city. Soon B&O president John Work Garrett received letters from Virginia's Governor John Letcher telling the B&O to pass no federal troops destined for any place in Virginia over the railroad, and threatening to confiscate the lines. Charles Town, West Virginia, Charles Town's mayor also wrote, threatening to cut the B&O's main line by destroying the long bridge over the Potomac River at Harpers Ferry, and Garrett also received anonymous threats. Thus he and others asked Secretary of War Cameron to protect the B&O as the national capitol's main westward link. Cameron instead warned Garrett that passage of any rebel troops over his line would be treason. The Secretary of War agreed to station troops to protect the North Central, the Pennsylvania Railroad, and even the PW&B, but flatly refused to help the B&O, his main competition. The B&O had to repair damaged line at its own expense, and often received late or no payment for services rendered to the federal government. In May, CSA Colonel Jackson's operations against the B&O Railroad (1861) began. Stonewall Jackson initially permitted B&O trains to operate during limited hours over the approximately from Point of Rocks to Cumberland. On June 20, 1861, Jackson's Confederates seized Martinsburg, a major B&O work center, having blown up the Harpers Ferry railroad bridge on June 14. Confederates confiscated dozens of locomotives and train cars and ripped up double track in order to ship rails for Confederate use in Virginia (14 locomotives and 83 rail cars were dismantled and sent south, and another 42 locomotives and 386 rail cars damaged or destroyed at Martinsburg, with the B&O water station and machine shops also destroyed and miles of telegraph wire removed by the time federal control was restored in March 1862). By the end of 1861, 23 B&O railroad bridges had been burned and of track were torn up or destroyed. Since Jackson cut the B&O main line into Washington for more than six months, the North Central and Pennsylvania Railroads profited from overflow traffic, even as many B&O trains stood idle in Baltimore. Garrett tried to use his government contacts to secure the needed protection, from Maryland Delegate Reverdy Johnson to General George McClellan and Treasury Secretary Salmon P. Chase. As winter began, coal prices soared in Washington, even though the B&O in September arranged for free coal transport from its Cumberland, Maryland, terminal down the C&O Canal (which reduced prices somewhat, although Confederates also damaged the C&O canal that winter). Furthermore, western farmers could not get their produce to markets because of the B&O shutdown, only partially alleviated by the summer 1861 Union army victories at the Battle of Philippi (West Virginia) and Battle of Rich Mountain, Rich Mountain, and vigorous army and company work crews which reduced the main-line gap to 25 miles between Harpers Ferry and Back Creek. Finally at year end, Samuel Morse Felton Sr., Samuel M. Felton, the PW&B President, wrote newspapers about the War Department's discrimination against his cooperating railroad line, which competed with Cameron's favored North Central and Pennsylvania Railroads. President Lincoln (familiar with railroad law since his days as an Illinois lawyer) in January 1862 replaced Cameron with Pennsylvania lawyer Edwin M. Stanton, who had been serving as Cameron's legal advisor. Furthermore, on January 31, 1862, Congress passed the Railways and Telegraph Act of January 31, 1862, creating the United States Military Railroad and allowing it to seize and operate any railroad or telegraph company's equipment, although Stanton and USMRR Superintendent Daniel McCallum would take a "team of rivals" approach to railroad management and allow civilian operations to continue. In February 1862, Union forces recaptured Martinsburg and Harpers Ferry, and work crews continued replacing wrecked bridges and equipment, although bushwhacker raids continued. Even then train movements were sporadic and subject to frequent stoppages, derailments, capture and attack. Prominent raids on the B&O railroad during this period were: * The Great Train Raid of 1861, May 22 – June 23, 1861 * The Romney Expedition, January 1 through January 24, 1862 * Operations during the Maryland Campaign, September 8, 1862 * Various raids of Brigadier General Albert G. Jenkins, A. G. Jenkins, Fall, 1862 :


1863–1865

The second half of the Civil War was characterized by near-continuous raiding, which severely hampered the Union defense of Washington, D.C. Union forces and leaders often failed to properly secure the region, despite the B&O's vital importance to the Union cause. This military strategy, or lack thereof, allowed Confederate commanders to contribute significantly to the length of the war, by conducting free-ranging military operations against the region and railroad. Before the Battle of Monocacy, B&O agents began reporting Confederate troop movements eleven days prior to the battle, and Garrett had their intelligence passed to authorities in the War Department and to Major General Lew Wallace, who commanded the department responsible for defense of the area. As preparations for the battle progressed, the B&O provided transport for federal troops and munitions, and on two occasions Garrett was contacted directly by President Abraham Lincoln for further information. Though Union forces lost this battle, the delay allowed Ulysses S. Grant to successfully repel the Confederate attack on Washington at the Battle of Fort Stevens two days later. After the battle, Lincoln paid tribute to Garrett as: * The Jones-Imboden Raid, April 24 through May 22, 1863 * The Catoctin Station Raid, June 17, 1863 * The First Calico Raid, June 19, 1863 * The B&O Raid on Duffield Station, January 1864 * The McNeill's Rangers, McNeill Raid, May 5, 1864 * The Action at Mount Zion Church#The 2nd Calico Raid, Second Calico Raid, July 3, 1864 * The Battle of Monocacy, July 9, 1864 * Gilmor's Raid, July 11, 1864 * The Greenback Raid, by 43rd Battalion Virginia Cavalry, Mosby's Rangers on October 14, 1864 * The B&O Raid on Duffield Station II, January 1865 * Gilmor's B&O Raid, February 1865 * The B&O Derailment Raid, March 1865 The Confederate leaders who led these operations and specifically targeted the railroad included: * Lieutenant General Thomas J. Stonewall Jackson, "Stonewall" Jackson and many units under his command * Lieutenant General Jubal Anderson Early and many units under his command * Brigadier General Turner Ashby and his "Black Horse" cavalry * Brigadier General John D. Imboden and the 62nd Virginia Mounted Infantry (1st Partisan Rangers) * Brigadier General Albert G. Jenkins and the 8th Virginia Cavalry * Brigadier General William E. Jones (general), William E.

Westward by merger

A steel and stone bridge was built across the Ohio River between Bellaire, Ohio, and Wheeling, West Virginia, in 1871, connecting the B&O to the Central Ohio Railroad, which the B&O had leased starting in 1866. This provided a direct rail connection to Columbus, Ohio, and the lease marked the beginning of a series of expansions to the west and north. Other railroads included in the B&O were: * Winchester and Potomac Railroad and Winchester and Strasburg Railroad from 1867. This pair of lines connected with the B&O at Harper's Ferry, West Virginia, and constituted the only significant B&O trackage in present-day Virginia. * Sandusky, Mansfield and Newark Railroad leased through the Central Ohio in 1869 * Pittsburgh and Connellsville Railroad from 1871. This was the B&O entry into Pittsburgh, thwarting the denial of a Pennsylvania charter to the B&O. * Somerset and Cambria Railroad from 1879 * Buffalo Railroad from 1880 * Pittsburgh Southern Railroad acquired 1883. Originally a narrow-gauge railroad, it was converted to standard gauge and renamed the Baltimore & Ohio Short Line. * West Virginia and Pittsburgh Railroad from 1890 * Columbus and Cincinnati Midland Railroad leased through the Central Ohio in 1890 * Monongahela River Railroad from 1900 * Marietta and Cincinnati Railroad from 1882. This was initially renamed the Cincinnati, Washington and Baltimore Railroad and then again to the Baltimore and Ohio Southwestern Railroad in 1889. The B&OSW absorbed the

This was originally a Narrow-gauge railway, narrow-gauge system which was standard gauged from 1883 to 1911. It formed the main B&O line west from Pittsburgh. The line passed the Mars Station, Pennsylvania, Mars Train Station in Mars, Pennsylvania, northwest of Pittsburgh. * Valley Railway, Cleveland, Terminal and Valley Railway from 1895. This was the B&O's entry into Cleveland, Ohio. * Cleveland, Lorain and Wheeling Railroad from 1909 * Chicago Terminal Transfer Company, reorganized in 1910 as the Baltimore and Ohio Chicago Terminal Railroad. This switching line was always operated as a separate company. * Salisbury Railroad near Pittsburgh, operated from 1912 * Cincinnati, Hamilton and Dayton Railway (1895–1917), Cincinnati, Hamilton and Dayton Railroad from 1912 * Morgantown and Kingwood Railroad from 1920 * Coal and Coke Railway from 1916 * Cincinnati, Indianapolis and Western Railroad from 1927. This was originally part of the Cincinnati, Hamilton and Dayton, and gave the B&O a connection to Springfield, Illinois. * Buffalo, Rochester and Pittsburgh Railway in 1932. This gave the B&O a line into New York state. * Buffalo and Susquehanna Railroad from 1932. Part of the line was severed from the rest of the system by flooding, and became part of the Wellsville, Addison and Galeton Railroad in 1955. (This list omits certain short lines.) The Chicago and Alton Railroad was purchased by the B&O in 1931 and renamed the Alton Railroad. It was always operated separately and was eventually bought by the Gulf, Mobile and Ohio Railroad after receivership in 1942.


Great Railroad Strike of 1877

As a result of poor national economic conditions in the mid-1870s following the Panic of 1873, the B&O attempted to reduce its workers' wages. After a second reduction in wages was announced in the same year, workers began the Great Railroad Strike of 1877 on July 14 in Martinsburg, West Virginia. Striking workers would not allow any of the trains, mainly freight trains, to roll until the third wage cut was revoked. Governor of West Virginia, West Virginia Governor Henry M. Mathews sent in state militia units to restore train service but the soldiers refused to fire on the strikers. The strike spread to

staged a sympathy strike that was also met with an assault by the state militia; Pittsburgh then erupted into widespread rioting. The strike ended after federal troops and state militias restored order.


New lines in Maryland

In 1866 the B&O began constructing the Metropolitan Subdivision, Metropolitan Branch west out of Washington, which was completed in 1873 after years of erratic effort. Before this line was laid, rail traffic west of Washington had to travel first to Relay or Baltimore before joining the main line. The line cut a more or less straight line from Washington to Point of Rocks, Maryland, with many grades and large bridges. Upon the opening of this line, through passenger traffic was rerouted through Washington, and the Old Main Line from Point of Rocks to Relay was reduced to secondary status as far as passenger service was concerned. The Washington to Gaithersburg, Maryland, Gaithersburg section of the Met Branch was double-tracked during 1886–1893. Rebuilding in the early 20th century and complete double-tracking of the branch by 1928 increased capacity; the "branches" became the ''de facto'' mainline, though the Old Main Line was retained as a relief route. Meanwhile, the

and New York City, New York. The state of Maryland had stayed true to its implicit promise not to grant competing charters for the Baltimore/Washington line, but when a charter was granted in 1860 to build a line from Baltimore to Popes Creek, Maryland, Pope's Creek in southern Maryland, lawyers for the Pennsylvania RR picked up on a clause in the unfulfilled charter allowing branches up to long, from any point and in any direction. The projected route, passing through what is now

, could have a "branch" constructed that would allow service into Washington. The Pennsylvania picked up the charter through the agency of the Baltimore and Potomac Railroad and in 1872 service between Baltimore and Washington began. (''See'' Pope's Creek Subdivision.) At the same time, the PRR outmaneuvered the B&O and took control of the Long Bridge (Potomac River), Long Bridge across the Potomac River into Virginia, the B&O's connection to southern lines. In response, the B&O chartered the Philadelphia Branch in Maryland and the Baltimore and Philadelphia Railroad in Delaware and Pennsylvania and built a parallel route, finished in 1886. The 10th president, Charles F. Mayer (railroad president), Charles F. Mayer, spearheaded the development of the Baltimore Belt Line, which opened in 1895, and recruited engineer Samuel Rea to design it. This belt line connected the main line to the Philadelphia Branch without the need for a train ferry, car ferry across the Patapsco River, but the cost of constructing the Howard Street Tunnel drove the B&O to bankruptcy in 1896. Two other lines were built in attempts to reconnect to the south. The Alexandria Branch (now called the Capital Subdivision#Alexandria Extension, Alexandria Extension) was built in 1874, starting from Hyattsville, Maryland, and ending at a ferry operation at Shepherd's Landing. The ferry operation continued until 1901 when the trackage rights agreement concluded as part of the construction of Washington Union Station saw the south end of the branch realigned to link to the PRR trackage in Anacostia, across the Anacostia Railroad Bridge, into the Virginia Avenue Tunnel, through Southwest Washington, D.C., to Potomac Yard in Alexandria, Virginia. (''See'' RF&P Subdivision.) The Alexandria Branch trackage to Shepherd's Landing was heavily used during World War II when traffic congestion on the Long Bridge (Potomac River), Long Bridge caused the U.S. Army Corps of Engineers to construct a bridge along the original plan of the B&O: Alexandria to Shepherd's Landing, Washington. Trains of empty freight cars were routed north and south over the structure, which was demolished after the end of World War II.National Railway Historical Society, Washington, D.C. Chapter

Before either connection was made, however, another branch was built around the west side of Washington. During the 1880s the B&O had organised a group of bankrupt railroads in Virginia into the Virginia Midland Railroad. The VM track ran from Alexandria, Virginia, Alexandria to Danville, Virginia. The line projected west across the Potomac River was intended to cross the Potomac just north of the D.C. line, to continue southwest to a connection with the B&O-controlled Virginia Midland (VM) in Fairfax, Virginia, Fairfax (now Fairfax Station, Virginia, Fairfax Station, to distinguish it from what was Fairfax Court House, Virginia, Fairfax Court House and is now the City of Fairfax, Virginia), and if possible to a connection with the Richmond, Fredericksburg and Potomac Railroad in Quantico, Virginia, Quantico. The branch was started in 1892 and reached Chevy Chase, Maryland, the same year. Financial problems in both the VM and B&O forced a halt to construction and led to the B&O's loss of control of the VM. Following bankruptcy, and control by the Pennsylvania Railroad, by the time the line was completed in 1910 there was no longer any point to the river crossing. Thus, the renamed Metropolitan Subdivision#Georgetown Branch, Georgetown Branch came to serve a wide range of customers in Maryland and in Georgetown, Washington, D.C., Georgetown, such as the Potomac Electric Power Company, the Washington Milling Company, and the U.S. government. The line cut directly across various creeks, and includes what was said to be the longest wood Trestle bridge, trestle on the railroad over Rock Creek (Potomac River), Rock Creek; and a short tunnel, Dalecarlia Tunnel, under the Washington Aqueduct. The line was almost completely abandoned in 1986 by CSX and is presently used in part as the right-of-way for the Capital Crescent Trail. After a flood damaged the C&O Canal in 1877, the B&O acquired a majority interest in the canal mainly to keep its property and right of way from potential use by the Western Maryland Railroad. The canal was operated by the B&O until 1924 when it was damaged in another flood. The canal's property was later transferred to the U.S. government in 1938 in consideration for obtaining a loan from the federal Reconstruction Finance Corporation. In 1895 the B&O introduced electric locomotives over of line near Camden, initially using an overhead electric slot system.


The 20th century

Following its emergence from bankruptcy, control of the B&O was acquired by the Pennsylvania Railroad in 1901, though the two kept separate corporate identities. A rising young PRR Vice President, Leonor F. Loree, was appointed president. Loree shared the Pennsy management's belief in infrastructure and the B&O at that time needed some of that. New classes of engines were built to haul longer, heavier trains faster. The Old Main Line was reworked, sections of the original right-of-way cut off by the straightening of curves and replacement of old, weight-restricted bridges with newer, heavier bridges. Most of Loree's work on the B&O physical plant remains evident today. Many iron and steel bridges on the railroad were replaced with stone (Pennsy preferred stone to the preference of the Reading Company, Reading and Lackawanna Railroad for concrete). With the adoption of anti-trust legislation in 1906, the relation between the two companies was severed. The railroad's passenger numbers were at a disadvantage with the railroad's major competitor in the northeast, the

Suffering from its weaker market position from Baltimore to New York, the B&O discontinued all passenger service north of Baltimore on April 26, 1958. One day later, the railroad had declared itself fully dieselized. The Chesapeake and Ohio Railway took financial control of the B&O in 1963. On May 1, 1971, Amtrak had taken over all of the remaining non-commuter routes of the B&O. The B&O already had a controlling interest in the Western Maryland Railway. In 1973 the three railroads were brought together under one corporate identity, the Chessie System, although they continued to operate as separate railroads. In 1980 the Chessie System and Seaboard Coast Line Industries, a holding company that owned the Seaboard Coast Line, the Louisville & Nashville, the Clinchfield Railroad, Clinchfield, and the Georgia Railroad, agreed to form CSX Corporation.
