Ansaldo STS, through its subsidiary Ansaldo STS USA, received a $25.8 million contract from the Metropolitan Transportation Authority’s Long Island Railroad (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 II  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.
