There are plans to revive the "limited express" trains. The North–South Commuter Railway and the new South Main Line under the South Long Haul project will both feature "limited express" services. Both limited expresses will run on standard-gauge track and will use dedicated rolling stock capable of running of up to or higher-speed rail. For the North–South Commuter Railway (NSCR), an airport express train will connect Clark International Airport with Alabang station in Muntinlupa, skipping all the other stations in Central Luzon and only stopping at four other stations in Metro Manila. In comparison, the "Commuter Express" services on the NSCR will serve more stations but will use the same electric multiple units as the regular commuter service. To the south of the NSCR, the upcoming "Bicol Express" flagship service will only stop at major cities compared to the "Regional Express" and "Local/Commuter" services.
