[1] The FG&A connects with CSX at Baldwin, Pensacola, and Attapulgus; with the AN Railway at Chattahoochee; and with the Bay Line Railroad at Cottondale.

Amtrak service was suspended in 2005 due to damage to track and trestles by Hurricane Katrina, and has never resumed east of New Orleans.

The 373 miles of the Florida Gulf & Atlantic Railroad comprise the main line between Baldwin and Pensacola.

The Florida Gulf & Atlantic Railroad's Bainbridge Subdivision runs as a branch line between Tallahassee north to Attapulgus, Georgia.

[3] The Tallahassee Subdivision of the main line was first built as the Florida, Atlantic and Gulf Central Railroad from Lake City to Jacksonville in 1857.

The line was only intended to be a shortline for logging, but since it provided an additional rail route from Georgia into Florida, traffic increased.

This is due to the fact that the numbering still reflects the line's full length to Carrabelle, which was mile 0 before the track between there and Tallahassee was abandoned.
