The Valley Interlocking Signal Cutover Project brings state-of- the-art technology to this critical LIRR location by replacing the early 20th century relay-based signal technology with a modern microprocessor based system. In addition, 30 switches in the area were modernized with electronic components replacing the outdated mechanical ones. The cost of the project is approximately $60 million. Funding is provided by the MTA LIRR Capital Improvement Program and the Federal Transit Administration.

"This weekend outage is needed as part of our ongoing effort to modernize the LIRR's signal system, which controls train traffic," said LIRR President Helena Williams. "When it is completed it will mean fewer maintenance-related delays and better service for our customers."
