MTA New York City Transit (NYCT) continues to make USD 774 million worth of critical improvements on the metro Line 7 and is on target to increase the line’s capacity and reliability with a new high-tech signal system.
The work includes replacement of both underground and elevated tracks, and critical replacement of the existing fixed-block signal system on the line with modern signal technology. New signals will allow for the use of Communications-Based Train Control (CBTC).
Nearly every element of the Line 7 is seeing improvements. In April 2016, reconstruction and fortification of the Steinway Tunnel was completed, bringing it back to a state of good repair after it had suffered saltwater damage from Superstorm Sandy in 2012.
