The Mindanao Railway, previously known as the Trans-Mindanao High Speed Railway, is a proposed railway system in Mindanao, the southernmost major island of the Philippines. Originally proposed in 1936 as part of Manuel L. Quezon's efforts to strengthen the presence of Commonwealth government in Mindanao against the rising influence of Imperial Japan before World War II, the line was shelved. Other proposals and studies were made in the 1950s, 1990s, and the 2000s, but never materialized. The current line began development in 2018; however, construction has yet to start. It will be initially built as a single-track standard gauge system to be operated by diesel-powered rolling stock, but will have provisions for upgrading to double-track and electrification through overhead lines.
