They Left This Forgotten ALCO RSD-15 'Alligator' to Die... Then It Roared Back to Life!

Deep inside a forgotten locomotive scrapyard, one machine sat waiting for the scrapper's torch — a rare 1959 ALCO RSD-15, nicknamed the "Alligator" for its legendary long, low nose. Only 75 of these six-axle giants were ever built by ALCO, and today, most are gone forever. In this full-length restoration documentary, follow the Rider Auto team from the moment they discover this rusted 170-ton survivor buried under decades of decay, through the dramatic heavy-crane extraction, the highway convoy, and the complete teardown of its massive 2,400-horsepower ALCO 251B V16 diesel engine. Watch every stage of this rare locomotive restoration: sandblasting the frame back to bare metal, rebuilding the turbocharger and traction motors, a full cab reconstruction, and the historic Santa Fe Blue & Yellow repaint that brings this "Alligator" back to its original glory. It all builds to the moment no one thought would happen again — the first engine start in over 40 years, followed by its triumphant maiden run down the main line.
