Long Island Rail Road (LIRR) is a commuter rail system in southeastern New York, stretching from Manhattan to Long Island. The LIRR is the only commuter passenger railroad in the United States that operates 24/7 and is the busiest rail in North America. Long Island Rail Road contacted PS&C to support their Frequency Conversion needs as they required unique frequencies to power their rail signaling system.

LIRR required almost a dozen Rotary Frequency Converters to provide 25Hz and 100Hz throughout the whole rail system. PS&C is one of the only Frequency Converter manufacturers in the world that could meet the requirement and was known to LIRR from successfully supporting their operations previously. We are proud to help power the mass rail market and look forward to our continued support of LIRR.
