Brightline is an express intercity rail system in Florida, United States. Developed and operated by All Aboard Florida, a wholly owned subsidiary of Florida East Coast Industries (FECI), Brightline is the United States' only privately owned and operated intercity passenger railroad and its first since 1983 (when the Denver & Rio Grande Western Railroad discontinued the Rio Grande Zephyr).
Brightline's service runs between Miami and West Palm Beach with a single intermediate stop at Fort Lauderdale. The Fort Lauderdale–West Palm Beach segment opened on January 13, 2018, followed by Fort Lauderdale–Miami on May 19. An extension from West Palm Beach to Orlando via Cocoa is scheduled to open in 2021, and more extensions are planned.
Brightline's diesel–electric locomotive-hauled trains run alongside freight trains in a shared-use corridor that was upgraded from a pre-existing Florida East Coast Railway (FEC) freight train corridor. The future West Palm Beach–Cocoa segment will be constructed in a similar fashion, while 40 mi (64 km) of new track will be constructed in the State Road 528 corridor for the remainder of the extension, between Cocoa and Orlando International Airport.
On September 18, 2018, Brightline announced the acquisition of XpressWest, a private company with the goal of connecting Las Vegas with Southern California via Victorville, California. Brightline announced the intent of purchasing 38 acres of land near the Las Vegas Strip for a station and following the Interstate 15 corridor from Las Vegas to Southern California with the initial journey projected for 2022.
