Context paragraphs:
Atlantic Coastline Railroad Passenger Depot: The Atlantic Coastline Railroad Passenger Depot is a historic train station in Dothan, Alabama.  By 1907, the town had outgrown its depot, and the freight depot had to be pressed into passenger service.  When the new depot was completed, it was the largest and busiest on the Atlantic Coast Line Railroad between Montgomery, Alabama, and Thomasville, Georgia.  The Atlantic Coast Line merged with the Seaboard Air Line Railroad in 1967 to form the Seaboard Coast Line Railroad.  Passenger service to Dothan ended in 1979.

Gulf Wind: The Gulf Wind was a streamlined passenger train inaugurated on July 31, 1949, as a joint operation by the Louisville and Nashville Railroad and the Seaboard Air Line Railroad (Seaboard Coast Line after merger with the Atlantic Coast Line on July 1, 1967).  The "Gulf Wind" replaced the heavyweight "New Orleans - Florida Limited" as the premier train on this routing.  For much of the twentieth century, one or two other passenger trains, numbered but unnamed, also plied this route daily; these were much-slower local trains, stopping at each small town along the route, and were labeled simply as "passenger, mail, and express" in timetables.

Florida West Shore Railway: The Florida West Shore Railway was a subsidiary of the Seaboard Air Line Railroad that expanded their rail system south to Sarasota in the early 1900s.  The Seaboard Air Line Railroad had just expanded to Tampa by acquiring the Florida Central and Peninsular Railroad in 1901, which became Seaboard's main line.

Silver Meteor: The Silver Meteor is a passenger train operated by Amtrak between New York City and Miami, Florida.  The first diesel-powered streamliner between New York and Florida, since being introduced by the Seaboard Air Line Railroad (SAL) in 1939, it remains in operation now.  The train is part of Amtrak's "Silver Service" along with the "Silver Star", another former SAL streamliner.

Camden station (South Carolina): Camden, also known as the Seaboard Air Line Railroad Depot, is a train station in Camden, South Carolina.  It serves Amtrak, the national passenger rail service.  The station was built by the Seaboard Air Line Railroad in 1937.  It is located on 1100 West DeKalb Street (US 1), although some sources give the address as being at 1060 West DeKalb Street.  Either way, it was named to the National Register of Historic Places in 2000.  The station is in disrepair, and a renovation project is scheduled to commence in August 2014. The station renovations were completed in early 2016.

Dillon station: Dillon is a train station in Dillon, South Carolina, served by Amtrak, the United States' railroad passenger system.  It was originally built by the Florence Railroad in 1893, but only as a freight station.  Once the railroad was consolidated into the Atlantic Coast Line Railroad in 1898, the passenger station was opened in 1904.  The station survived the merger of the Atlantic Coast Line and Seaboard Air Line Railroads into the Seaboard Coast Line Railroad in 1967, only to terminate passenger service in 1971.  Amtrak service to Dillon began on June 15, 1976, with the introduction of the "Palmetto".  The four-faced station clock also contains two Fahrenheit thermometers.

Seaboard Air Line Railroad Passenger Station: Seaboard Air Line Railroad Passenger Station is a historic train station located at Charlotte, Mecklenburg County, North Carolina.  It designed by noted architect Charles Christian Hook and built by the Seaboard Air Line Railroad in 1896.  It was extensively renovated and enlarged in 1916-1917.  The red brick and pink stucco building consists of a two-story central section with one-story extensions.  It features a wide umbrella shed that extends 300 feet along the trackside and is supported by 15 cast iron columns.  Passenger service ceased in 1958, and the building housed yard offices for the Seaboard Coastline.  It currently houses a homeless shelter.

Sebring station: Sebring (also known as the Old Sebring Seaboard Air Line Depot and the Seaboard Air Line Passenger Station) is a historic train station in Sebring, Florida, United States.  It is currently served by Amtrak, the national railroad passenger system.  Located on East Center Avenue, the station was constructed in 1924 by the Seaboard Air Line Railway.

Champion (train): The Champion was a streamlined passenger train operated by the Atlantic Coast Line Railroad and Florida East Coast Railway between New York City and Miami or St. Petersburg, Florida.  It operated from 1939 until 1979, continuing under the Seaboard Coast Line and Amtrak.  It was a direct competitor to the Seaboard Air Line Railway's "Silver Meteor", the first New York-Florida streamliner.

Seaboard Air Line Railroad: The Seaboard Air Line Railroad (reporting mark SAL) , which styled itself "The Route of Courteous Service," was an American railroad whose corporate existence extended from April 14, 1900 until July 1, 1967, when it merged with the Atlantic Coast Line Railroad, its longtime rival, to form the Seaboard Coast Line Railroad.  The company was headquartered in Norfolk, Virginia, until 1958, when its main offices were relocated to Richmond, Virginia.  The Seaboard Air Line Railway Building in Norfolk's historic Freemason District still stands and has been converted to luxury apartments.
