Ansaldo STS, through its subsidiary Ansaldo STS USA, has received a $25.8 million contract from Metropolitan Transit Authority's (MTA) Long Island Rail Road (LIRR) for the Harold and Point 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 Ansaldo STS USA has implemented for the LIRR using the MicroLok II platform, including the Wood, Jamaica, and Amityville and Wantagh interlockings.
