Why we’re doing it
The Crosstown Line, used by the train, still has its original signal system from when it opened over 90 years ago. This system is now past the end of its useful life. So, we’re bringing the latest in communications-based train control (CBTC) technology to the Crosstown Line. A more modern, reliable signal system means more reliable service for the 160,000 riders who take the each day.
We’re partially suspending service 24/7 in three phases because this will allow us to complete the work much more quickly than working only overnight or on weekends. This will help us reach our goal of fully upgrading the signal system on the Crosstown Line by 2027.
