in the planning stages and no funding has been identified for its implementation. All routes in the in-depth study start in downtown Jacksonville and head out in one of three directions: North (to Yulee), South (to Green Cove Springs), and Southeast (to St. Augustine). The North Corridor originates in Downtown Jacksonville, and heads North along the abandoned S-Line to the CSX Kingsland division line to Yulee, FL. The Kingsland division line is a remnant of the Seaboard Air Line's mainline. The route passes two miles (3 km) from Jacksonville International Airport. The Southwest Corridor originates in Downtown Jacksonville, and heads South along the CSX A-Line to Green Cove Springs, FL. The Southeast Corridor originates in Downtown Jacksonville, and heads Southeast along the Florida East Coast Railway's main line to St. Augustine, closely following U.S. 1, known as Philips Highway in Jacksonville and Ponce de Leon Boulevard in St. Augustine . The proposed route would share the railbed with the northernmost part of a freight rail line to Miami. The heavily trafficked corridor already serves 17 regularly scheduled interregional freight trains per day, a figure which does not include Amtrak service, unscheduled freight trains, and other services. The 2009 feasibility study estimated that this route could carry an estimated 5,469 passengers in 2020 on trains between Jacksonville and St. Augustine. Travel time is estimated at 51 minutes end to end, comparable to travel time by car. Notable proposed stops along the route include the J. Turner Butler Freeway, The Avenues, Race Track Road/Nocatee, the massive mixed-use residential/commercial development at Palencia, West St. Augustine, the Northeast Florida Regional Airport (not to be confused with the much larger and busier Jacksonville International Airport almost 50 miles to the north), the St. Johns County Government Complex, and its terminus in Downtown St. Augustine.
