The Ronkonkoma to Yaphank Signalization project was to address some of the remaining areas of dark territory within the LIRR system. It is under review for inclusion in a future Capital Plan. Currently, the area east of Ronkonkoma is not signalized. This project will upgrade the Ronkonkoma to Yaphank segment, including installing track circuits and automatic speed control (ASC). Milestone dates are not available due to project still being under development.
