Flagler County, Florida: Flagler County is a county on the east coast of the U.S. state of Florida.  As of the 2010 census, the population was 95,696.  Its county seat is Bunnell.  Created in 1917 from portions of Saint Johns and Volusia Counties, it was named for Henry Morrison Flagler, who built the Florida East Coast Railway.

KTM East Coast Railway Line: The East Coast Railway Line is the single track metre gauge runs between Gemas railway station, in Negeri Sembilan and Tumpat railway station, in Kelantan of Malaysia.  Gemas is the rail junction between the West Coast line and East Coast railway line.  Like the West Coast Railway Line, it is called the East Coast Railway Line (Malaysia) because it serves two of Peninsular Malaysia's East Coast states, namely Pahang and Kelantan.  In fact, it does not run along the coast at all and only meets the South China Sea when it terminates in Tumpat railway station.  It runs through the interior, often through deep jungle, thus earning the nickname Jungle Railway.  Terengganu is the only state in Peninsular Malaysia not served by the KTM railway network.

Dixie Flagler: The Dixie Flagler was a streamlined passenger train operated by the Florida East Coast Railway (FEC) between Chicago, Illinois and Miami, Florida.  It began in 1939 as the Henry M. Flagler, a regional service between Miami and Jacksonville, Florida; the FEC renamed it and extended it to Chicago a year later.  As an overnight streamliner it was part of the every-third-day pool shared by the "City of Miami" and "South Wind".  It was renamed Dixieland in 1954 and discontinued altogether in 1957.

Old Flagler County Courthouse: The Old Flagler County Courthouse is an historic two-story redbrick courthouse building located at 200 East Moody Boulevard in Bunnell, Florida.  Designed by Wilbur Talley in the Classical Revival style, it was built in 1924 by O. P. Woodcock to serve Flagler County which had been created in 1917.  It was the county's second courthouse building and its first purpose built one.  In 1985 a three-story addition was attached to its rear.  In January 2007 the 1924 building was closed due to safety problems with its roof.  By January 2008, the 1985 addition had also been vacated due to structural problems.  Courthouse operations are now housed at the Kim C. Hammond Justice Center 1769 East Moody Boulevard.

The Breakers (hotel): The Breakers Palm Beach is a historic hotel in Palm Beach, Florida, United States.  First known as The Palm Beach Inn, it was opened on January 16, 1896 by oil, real estate, and railroad tycoon Henry Flagler to accommodate travelers on his Florida East Coast Railway.  It occupies the beachfront portion of the grounds of the Royal Poinciana Hotel, which Flagler had opened beside Lake Worth Lagoon facing the inland waterway in 1894.  Guests began requesting rooms "over by the breakers," so Flagler renamed it The Breakers Hotel in 1901.  The wooden hotel burned on June 9, 1903 and was rebuilt, opening on February 1, 1904.  Rooms started at $4 a night, including three meals a day.  Because Flagler forbade motorized vehicles on the property, patrons were delivered between the two hotels in wheeled chairs powered by employees.  The grounds featured a nine-hole golf course.  The hotel is located at 1 South County Road.

Flagler County Airport: Flagler County Airport (ICAO: KFIN, FAA LID: FIN) is a county-owned public-use airport located three miles (5 km) east of the central business district of Bunnell, a city in Flagler County, Florida, United States.  The airport's former FAA location identifiers were X47 and XFL.  The airfield was originally constructed by the United States Navy during World War II as Naval Outlying Field Bunnell (NOLF Bunnell), an auxiliary airfield for flight training operations originating from nearby Naval Air Station Jacksonville, NAS Daytona Beach and NAS DeLand.  Following the end of the war, the airfield was transferred from the Navy to Flagler County for use as a general aviation airport.

Seaboard-All Florida Railway: The Seaboard-All Florida Railway was a subsidiary of the Seaboard Air Line Railroad that oversaw two major extensions of the system in the early 1920s to southern Florida on each coast during the land boom.  One line extended the Seaboard's tracks on the east coast from West Palm Beach down to Miami (and later, Homestead), while the other extension on the west coast extended the tracks from Fort Ogden south to Fort Myers and Naples, with branches from Fort Myers to LaBelle and Punta Rassa.  These two extensions were heavily championed by Seaboard president S. Davies Warfield (who died months after its completion), and were constructed by Foley Brothers railroad contractors.  Both extensions also allowed the Seaboard to better compete with the Florida East Coast Railway and the Atlantic Coast Line Railroad, who already served the lower east and west coasts of Florida respectively.  Today, only the east coast route survives, though a few related structures from the abandoned west coast line still stand.

Florida East Coast Railway: The Florida East Coast Railway (reporting mark FEC) is a Class II railroad operating in the U.S. state of Florida and since 2007 has been a subsidiary of Railroad Acquisition Holdings, LLC, itself a subsidiary of Fortress Investment Group, LLC.

Overseas Highway: The Overseas Highway is a 113 mi highway carrying U.S. Route 1 (US 1) through the Florida Keys.  Large parts of it were built on the former right-of-way of the Overseas Railroad, the Key West Extension of the Florida East Coast Railway.  Completed in 1912, the Overseas Railroad was heavily damaged and partially destroyed in the Labor Day Hurricane of 1935.  The Florida East Coast Railway was financially unable to rebuild the destroyed sections, so the roadbed and remaining bridges were sold to the state of Florida for $640,000.
