Ansaldo STS was awarded a $42m contract from Long Island Rail Road (LIRR) to design and build a new signalling system using computer-based train control.

The scope of the contract for Ansaldo STS will include the supply of its MicroLok® II multipurpose wayside controller for various vital (safety-critical) and non-vital functions, power frequency (PF) track circuits, ethernet communications systems, and digital signal transmitters/receivers. The MicroLok II systems, which manage switches, signals, track circuits and other devices, will be deployed in ‘Redundant Hot Standby’ configuration for exceptional reliability. Similar MicroLok II systems have already been installed on other LIRR lines.

Ansaldo STS’s signal system will serve the LIRR’s existing 18-mile line between Ronkonkoma and Farmingdale which includes 5.3 miles of double-track. It will also serve the new 12.7 miles of additional double track currently under construction creating a continuous 18 mile double track corridor with eight interlockings (controlled by MicroLok II), seven stations, highway crossings and freight railroad sidings.

Ansaldo STS is proud to support LIRR’s commitment to quality systems and the safety of their passengers, employees and community.

Ansaldo STS is a leader in the global rail market, with over a century of experience in developing and supplying cutting-edge technologies in the Americas, Australia, and around the world.
