The Long Island Rail Road is a commuter rail system in the southeastern part of the U.S. state of New York, stretching from Manhattan to the eastern tip of Suffolk County on Long Island. It is the busiest commuter railroad in North America and one of the world’s few commuter systems that runs 24/7 year-round.
Continuing to improve on success in 2020, The LIRR added a second 25mph LaserTrain and increased the running speed to cover more of the network daily. Both LaserTrains operated up to 18 hours per day, cleaning 2/3rds of the network. To minimize slip-sliding, all vital parts were cleaned every 24 hours. Treatment was effective, with 88% less slipping trains after 12 hours, and instances that did occur were mainly on sections that were not cleaned by the LaserTrain.
Compared with 2019, LIRR reported:
reduction in low-adhesion delays
less cars taken out of service due to flat wheels
reduction in wheel truing labor costs (or $102,000) in October-November alone
on-time performance in November – an improvement of 4.6 percentage points
Less wheel truing results in longer wheel life. The LIRR have calculated that for each year of extended life, $500,000 in shop labor and materials costs will be saved.
In 2021, The LIRR announced their best annual on-time performance (OTP) since modern record-keeping began in the 1970s, with 96.3% of trains operating to schedule over the course of the year.
