The MTA apologized to customers Monday after a miscommunication about a tunnel construction project and a track error led to significant delays and frustrated customers along the D, N and R subway lines Monday morning.
The MTA began a structural rehabilitation project at tunnels in Brooklyn Monday - but it did not properly communicate those changes to riders beforehand, the agency said.
The agency says work on an approximately year-long project to repair and replace steel, concrete and tunnel lighting in the express tunnel between the 59th Street and 36th Street stations in Sunset Park began on Monday.
The repair work will cause N trains to make local stops at 45th Street and 53rd Street in both directions through at least July 2019, according to the MTA.
But according to NYC Transit Chief Customer Officer Sarah Meyer, the agency had "issues and challenges coordinating internally," and as a result, planned service changes were "not properly communicated to our customers."
With no advanced notice, riders were caught off guard.
(In a statement, Meyer said the blue wall is a construction barrier "which reduces our need to perform 'flagging' which slows trains down.")
Riders on Twitter also said that while the trains they were on were severely delayed, those delays were not reflected on the MTA's website.
