It is also the southernmost area on the PNR Metro Commuter Line to be upgraded to double track as a result of a proposed electrification scheme in 1978.

In 1978, the Japan International Cooperation Agency proposed the electrification of PNR's commuter services in Metro Manila.

Under PNR general manager Junn Magno's term, the Luzon Rail System was announced.

The move was made because it allows better access to technology from international suppliers, which in turn means faster trains and more frequent service according to the National Economic and Development Authority.

The second will be the PNR South Long Haul station building which will be built over the present one as part of Phase 4.

An indirect connection to the LRT Line 6 has also been proposed by a private-backed firm via Lake Front station under Phase 6C.
