Ansaldo STS, through its subsidiary Ansaldo STS USA, has received a $25.8 million contract from the Long Island Rail Road (LIRR) for the LIRR Harold and Point CIL’s (Central Instrument Location) Interlocking project.


This project, part of the LIRR East Side Access program, replaces the current vital relay-based interlocking control system with a MicroLok vital microprocessor-based system.

This switch to a microprocessor-based technology follows on the success of other upgrades ASTS USA has implemented for the LIRR using the MicroLok II platform, including the Wood, Jamaica, Amityville, and Wantagh interlockings.


Harold Interlocking, located just east of the East River which separates Manhattan from Queens, handles virtually all LIRR passenger train movements on the system, as well as Amtrak trains traveling between New York and Boston on the Northeast Corridor.
