Ansaldo STS was awarded a 42 million USD 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 Multi-Purpose wayside controller for various vital 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.
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.
