Philippine National Railways Metro Commuter Line

The Philippine National Railways Metro Commuter Line is one of the two commuter rail lines of the Philippine National Railways currently in service. Presently, the line contains thirty stations with 27 currently operational and 4 pending to be reopened. The line is colored orange on most maps.

The line runs in a general north-south direction from Caloocan or Tutuban to Calamba; linking the cities of Caloocan, Manila, Makati, Taguig, Parañaque, Muntinlupa, San Pedro, Biñan, Santa Rosa, Cabuyao, and Calamba. Passengers can transfer to the LRT Line 1 at Blumentritt station, while passengers can transfer to MRT Line 2 at Santa Mesa station and passengers can transfer to MRT Line 3 at EDSA station.

The Metro Commuter Line was known for many names such as PNR Metro Commuter Line, shortened to Metro Commuter, Metro South Commuter, Orange Line, Metrotrak, Metrotren, and Commuter Express or Commex. However, the orange color of the line dates back to its first major upgrade in the 1980s.

Route
The Metro Commuter Line is predominantly aligned and shares the path of the South Main Line or SouthRail which uses a dedicated right of way of its own. It terminates at Calamba Station despite having rails further towards Sorsogon due to that being served by different inter-provincial services such as the Bicol Express and Mayon Limited.

Rolling stock
Four types of rolling stock currently runs on the PNR Metro Commuter line: the Hyundai Rotem Diesel Multiple Units, the locomotive hauled JR 203 Electric multiple units, and the JR Kiha 52 Diesel multiple units. The line is also being served by the JR Kiha 59 (Kogane) unit which is called as the "Premiere Train" service which runs from Tutuban up to Mamatid. Due to the opening of the new Calamba Station building, the Premiere Train services are currently suspended until further notice.

Metro South Commuter
The Metro South Commuter (also known as MSC) is the main train service offered by PNR that run along the Metro South Commuter Line. The trains that are currently being used for this service are the 900 Series Locomotives, PNR 2500 Series Locomotives, 203 series EMUs donated by JR East, and the South KoreanHyundai Rotem DMUs. The MSC trains operates from 4:56 am to 9:16 pm everyday. The trips are reduced upon announcements.

Last December 2, Philippine Standard Time, the new Calamba Station was inaugurated. Later that night, the MSC1907 was extended up to the said station. The MSC1937 was also extended, but only up to Sta. Rosa Station.

Premiere Train
The Premiere Train is a special MSC service that operates from Monday to Friday, except holidays. The train being used in this special service is the KiHa 59"Kogane" train set, which is also from Japan. The train stops at selected stations only, namely Tutuban, Blumentritt, España, Sta. Mesa, Buendia, Pasay Road,EDSA (flagstop), Sucat, Alabang, San Pedro, Biñan, Santa Rosa, and Mamatid.

The service has 4 trips: MSC501, MSC702, MSC1555, and MSC1802.

The service is currently suspended due to the inauguration of the new station building of Calamba and due to the repairs of the trainset being used for this service.

Shuttle Service
The Shuttle Service was introduced on January 27, 2014. This service uses Hyundai Rotem DMUs and JR KiHa 52. There are 4 routes of the Shuttle Service, where trains stop at all stations along the routes. This train service was removed last May 23, 2014 to give way to maintenance servicing of the rolling stocks. Another reason was the 3 consecutive weeks of delays and cancellations of some train trips.

Integrated Luzon Railway
Plans on reviving the North Main Line or NorthRail line has been considered since the fall of the construction of the New Northrail High Speed Line using the same Right-of-Way. The plan includes the re-utilization of the Narrow Gauge Line from Caloocan to provinces in the North such as Bulacan, Pampanga, Tarlac, Pangasinan, and La Union which would include the re-extension of the Metro Commuter services back to Bulacan.

Manila Metro Commuter Line rehabilitation Phase 2
Plans on rehabilitating and doubletracking the second phase of the Metro Commuter Line from Alabang towards Calamba has been considered since the administration of Former President Gloria Macapagal-Arroyo following the rehabilitation of the Caloocan-Tutuban-Alabang segments or the first phase of the Metro Commuter Line rehabilitation. The first phase of the rehabilitation was funded via soft-loans or and ODA grant from South Korea which was supposedly also the plan for the Phase 2 but were shelved due to termination of the new administration. Rehabilitation of the Phase 2 stations is still on going but the double-tracking is shelved due to lack of funds.
