Context paragraphs:
Memphis and Charleston Railroad: The Memphis and Charleston Railroad, completed in 1857, was the first railroad in the United States to link the Atlantic Ocean with the Mississippi River.  Chartered in 1846, the 311 mi gauge railroad ran from Memphis, Tennessee to Stevenson, Alabama through the towns of Corinth, Mississippi and Huntsville, Alabama.  The portion between Memphis and LaGrange, Tennessee was originally to be part of the LaGrange and Memphis Railroad, chartered in 1838.  From Stevenson, the road was connected to Chattanooga, Tennessee via the Nashville and Chattanooga Railroad.  In Alabama, the railroad followed the route of the Tuscumbia, Courtland and Decatur Railroad between Tuscumbia and Decatur, the first railroad to be built west of the Appalachian Mountains.

Huntington, West Virginia: Huntington is a city in Cabell County and Wayne County in the U.S. state of West Virginia.  It is the county seat of Cabell County, and largest city in the Huntington-Ashland, WV-KY-OH Metropolitan Statistical Area, sometimes referred to as the Tri-State Area.  A historic and bustling city of commerce and heavy industry, Huntington has long-flourished due to its ideal location on the Ohio River at the mouth of the Guyandotte River.  It is home to the Port of Huntington Tri-state, the busiest inland port in the United States.  Surrounded by extensive natural resources, the industrial sector is based in coal, oil, chemicals and steel all of which support Huntington's diversified economy.  The city is a vital rail-to-river transfer point for the marine transportation industry.  Also, it is considered a scenic locale in the western foothills of the Appalachian Mountains.  This location was selected by Collis Potter Huntington as ideal for the western terminus of the Chesapeake and Ohio Railway, the predecessor of what would become CSX Transportation which still operates CSX Transportation-Huntington Division in the city to date.  The railroad founded Huntington as one of the nation's first planned communities to facilitate the railroad and other transportation related industries at the railways western terminus.  Developing fast after the railroad's completion in 1871, the site was previously a collection of agricultural homesteads, and is eponymously named for the railroad company's founder Collis Potter Huntington.  The first identifiable permanent settlement, Holderby's Landing, was founded in 1775 in the Colony of Virginia although the site had been sparsely settled by the French as early as 1609.  With the exception of the neighborhoods of Westmoreland and Spring Valley, most of the city is in Cabell County.

Chapman, Lawrence County, Kentucky: Chapman is an unincorporated community located in Lawrence County, Kentucky, United States on the eastern bank of the Levisa Fork River.  It is served by KY Route 2037.  A high volume railway line, operated by CSX Transportation, extends through its limits and continues in a southerly direction throughout southeastern Kentucky to western Virginia and points south.  Although its location is many miles from the nearest industrial employer, the railroad has served the community as a source of employment.  The railroad was first built through the community in 1880 by CSX's predecessor, the Chesapeake and Ohio Railway.  C&O employees who resided in Chapman caught the train as it passed through on its multiple daily runs where they reported to work.  Chapman, Kentucky is named after its first settler and prominent landowner David Chapman (1803–1845), a native of Montgomery, West Virginia.  Many of Chapman's descendants still reside in the community at this time.  Chapmansville, West Virginia, a city located on U.S. Route 119 about forty miles east of Chapman, was established in 1800 by David Chapman's uncle Ned Chapman, as he was its first postmaster and general store operator.  The Chapman surname is an anglicized version of the German name Kaufmann, the German word for merchant.  David Chapman's ancestors originally emigrated to North America from Kaufmann, Germany.  Chapman is located 10 mi south of Louisa, Kentucky.

Kavanaugh, Kentucky: Kavanaugh, Kentucky is an unincorporated community located in Boyd County, Kentucky, located along U.S. Route 23 directly north of the Lawrence County line.  In 1984, the original alignment of U.S. 23 was replaced with a modern four-lane highway.  CSX Transportation's Big Sandy Subdivision railroad tracks pass through the community.  The railroad was formerly operated by the Chessie System and its predecessor the Chesapeake and Ohio Railway Company.

Moulton Courthouse Square Historic District: The Moulton Courthouse Square Historic District is a historic district in Moulton, Alabama.  Moulton's development began in 1820, when it was chosen as the county seat of the newly formed Lawrence County.  The first courthouse was a log structure; a log jail on the west side of the square operated until 1911, when it was replaced with the current, 3-story brick jail and courthouse annex.  Due to its lack of rail and river connections, development around the square remained sparse.  The log courthouse was replaced in 1860 with a two-story, square building with Classical Revival details.  The cotton economy of Lawrence County rebounded after the Civil War with the construction of several cotton gins, though nearly all of the structures built along the square in the late 19th century were later razed and replaced.  The oldest extant buildings in the district were built in 1911: the three-story courthouse annex, and the two-story, stone faced Citizens' Bank building.  The northern part of Market Street, on the west side of the square, were constructed during the early 1920s.  Lawrence County's economy received a boost from New Deal programs, most notably the Tennessee Valley Authority's fertilizer program and construction of Wheeler Dam.  Most of the square's buildings were constructed during the late 1930s and 1940s, in contrast to most historic downtowns around the South.  The current courthouse was completed in 1936.  The district was listed on the National Register of Historic Places in 1998.

Walnut Ridge Commercial Historic District: The Walnut Ridge Commercial Historic District encompasses the historic town center of Walnut Ridge, Arkansas, the county seat of Lawrence County.  The district includes a four-block stretch of Main Street (United States Route 412) on the northwest side of the railroad tracks, and extends for one and sometimes two blocks on either side.  Walnut Ridge was founded as a railroad town in 1875, and soon became a leading economic center in the county.  Most of its historic downtown consists of vernacular commercial architecture dating to the late 19th and early 20th centuries, built of masonry and brick, and one or two stories in height.  Notable buildings include the 1924 Swan Theatre at 222 West Main Street, the 1935 Old Walnut Ridge Post Office at 225 West Main (now housing the "Times Dispatch"), and the 1965 Lawrence County Courthouse at 315 West Main, which replaced a c. 1900 structure.

Florida Railroad: The Florida Railroad was the first railroad to connect the east and west coasts of Florida, running from Fernandina to Cedar Key.  The line later became part of the Seaboard Air Line Railroad, and, where still in use, is operated by CSX Transportation and the First Coast Railroad.  The highway corridor of SR 24, US 301, and SR A1A closely parallels the former Florida Railroad.

United New Jersey Railroad and Canal Company: The United New Jersey Railroad and Canal Company (UNJ&CC) was a railroad company which began as the important Camden & Amboy Railroad (C&A) whose 1830 lineage began as one of the eight or ten earliest permanent North Americanrailroads, and among the first common carrier transportation companies whose prospectus marketed an enterprise aimed (with a priority or principally) at carrying passengers fast and competing with stagecoaches between New York Harbor and Philadelphia-Trenton.  Among the other earliest chartered or incorporated railroads, only the Mohawk and Hudson Railroad and Baltimore and Ohio Railroad were chartered with passenger services in mind.  Later after mergers as the UNJ&CC became a subsidiary part of the Pennsylvania Railroad (PRR) system in New Jersey by the later merger and acquisition of several predecessor companies in 1872; which purchases also included the PRR's main line to New York City ("now Amtrak's Northeast Corridor").  Prior to 1872, its main lines were the (C&A, below), the first railroad in New Jersey and one of the first railroad in the United States.

Chesapeake and Ohio Railway: The Chesapeake and Ohio Railway was a Class I railroad formed in 1869 in Virginia from several smaller Virginia railroads begun in the 19th century.  Led by industrialist Collis P. Huntington, it reached from Virginia's capital city of Richmond to the Ohio River by 1873, where the railroad town (and later city) of Huntington, West Virginia was named for him.

Oregon Portage Railroad: The Oregon Portage Railroad was the first railroad in the U.S. state of Oregon.  It originally ran for 4.5 mi , with an accompanying 7 mi of telegraph line, and was later extended to a length of 15 mi .  The railroad was located on the south bank of the Cascades canal of the Columbia River.  It ran from Tanner Creek (near where Bonneville Dam was later built) to the Cascade Locks, which were under construction in the later years of the railroad's operation.  Although the Oregon Portage was the first railroad in Oregon, it was not the first along the Columbia River.  Francis A. Chenoweth operated a rail line on the river's north bank in present-day Washington in 1851.
