Schedule for CP04 (N1 E&M) is not correct since it has not yet even entered procurement stage.
Malolos-CIA / Solis-Malolos projected operation - December 2024
Solis-Tutuban (November 2025?)
Solis-Blumentritt - August 2026
Blumentritt-Senate/DeptEd - January 2027
Alabang-Calamba - May 2027
Senate/DeptEd-Alabang - May 2028
Complete System - May 2028
Even though Solis-Blumentritt is just 1.1km, that section is still projected to take 4+ years probably due to project complexities (building over LRT station, relocation of Antipolo Street, etc.). Too bad since Blumentritt will be transfer station between NSCR and LRT-1.
The package with the MMSP interoperability is projected to take the longest to complete.
Of course all these dates are subject to change --- allow additional 1 to 2 years to each projected date to accommodate usual delays. Hopefully the entire system is completed by 2030.
