G trains Roll Between Greenpoint and Long Island City After Five-Week Absence

G Subway Line service was restored on Tuesday, September 2 in time for the post Labor Day morning rush. The five-week suspension between Court Sq and Nassau Av began July 25 and gave MTA New York City Transit maintenance crews the opportunity to make Fix&Fortify resiliency repairs to the tubes, flooded and badly damaged during Superstorm Sandy nearly two years ago.
MTA Chairman & CEO Thomas F. Prendergast and NYC Transit Carmen Bianco were on hand at Greenpoint Av to greet customers as they returned to their normal travel routines.  
“The storm’s devastating impact on our Subway network posed an enormous challenge which we continue to meet while working daily to rebuild and improve the system,” said Bianco. “Transit personnel from throughout the agency demonstrated an extremely high level of dedication in rebuilding the Greenpoint Tubes and their work is deeply appreciated.”
While service was suspended, the Department of Buses operated a shuttle service that ferried thousands of customers daily between Long Island City and Greenpoint. Meanwhile, crews from every major division of the Department of Subways worked on installing communication lines, laying new track and third rail, repositioning signals, rebuilding tunnel infrastructure and performing rehabilitation work on adjacent stations.  
“The timely resumption of G service and the infrastructure repairs completed during the shutdown is a testament to our team’s hard work,” said Joe Leader, Senior Vice President Department of Subways. “I thank each and every one of the hundreds of employees who worked so hard over the past five weeks to get the job done.”
The tubes suffered extensive damage during Superstorm Sandy as three million gallons of salt water washed into the tunnel, filling it to the ceiling.  Tracks and equipment were totally submerged and the tunnels’ pump controls, electrical, communications, fan control and signal equipment all suffered serious damage.  Power cables immersed in salt water corroded from the inside, while corrosion on rails and fasteners increased the potential for delay-causing failures.  
The controls for ventilation, lighting and communication systems were all destroyed and have yet to be restored to their full level of pre-Sandy reliability.  In Sandy’s immediate aftermath NYC Transit and agency contractors worked tirelessly to restore service as quickly as possible after the storm.  However, we immediately realized that more extensive work would be necessary to repair and rebuild these vital systems in order to ensure safe and reliable service.
Fix&Fortify work to return these and other components to pre-Sandy condition, while providing for improved resiliency and reliability, touched every aspect of the tunnel and its operations. Among the work completed prior to this morning’s restoration of service:

602 work trains deployed
During the work, resiliency program management were faced with the herculean challenge of scheduling and coordinating all the various work crews to ensure that not only did the work plan get completed, but that it was done so in as safe a manner as possible.
Sandy’s damage to the subway system was historic. The Fix&Fortify project is designed to restore and rebuild damaged infrastructure and the delicate equipment that was submerged, while reducing the system’s vulnerability in the event of future severe weather. Overall, the MTA has been allocated nearly $3.8 billion in funding from the Federal Transit Administration (FTA) for repair, resiliency, and disaster relief work.  
In addition to the work inside the Greenpoint Tubes, the MTA’s Fix&Fortify campaign will also address issues in other under river tubes to make the system more resilient. Planning and design work is also underway for flood mitigation at NYC Transit facilities in low-lying areas of Manhattan, Brooklyn and Queens as well as similar flood prevention and mitigation work at the entrances to several stations in Lower Manhattan.
