North–South Commuter Railway

The North–South Commuter Railway (NSCR), also known as the Clark–Calamba Railway, is a 147-kilometer (91-mile) commuter rail system under construction on the island of Luzon in the Philippines. Running from New Clark City in Capas, Tarlac, to Calamba, Laguna, with 36 stations and four services, the railway is designed to improve connectivity within the Greater Manila Area and will be integrated with the railway network in the region.

Originally planned in the 1990s, the railway project has had a tumultuous history, being repeatedly halted and restarted for various reasons. The first proposals were the 32-kilometer (20-mile) "Manila–Clark rapid railway" with Spain in the 1990s, alongside the "Manila–Calabarzon Express". During the 2000s, the Northrail project with China was initiated but discontinued in 2011 due to allegations of overpricing. The railway's current incarnation began development in 2013. The project's initial phase was approved in 2015, and construction began in 2019.

Expected to cost ₱873.62 billion, the line is the most expensive railway transportation project in the country. The entire system is expected to be completed by the third quarter of 2033.
