Florida High Speed Rail was a proposed government backed high-speed rail system that would have connected Miami, Orlando, and Tampa. The first phase was planned to connect Orlando and Tampa and was offered federal funding, but it was turned down by Governor Rick Scott in 2011. The second phase of the line was envisioned to connect Miami. By 2014, a private project known as All Aboard Florida by a company of the historic Florida East Coast Railway began construction of a higher-speed rail line in South Florida that is planned to eventually terminate at Orlando International Airport.

Answer this question, if possible (if impossible, reply "unanswerable"): What company is responsible for All Aboard Florida?
Florida East Coast Railway
