BROOKLYN (WABC) -- A train being used by MTA workers derailed in a Downtown Brooklyn subway tunnel early Thursday, causing delays for the morning commute.
The wheels of the second car of an eight-car northbound N train jumped the track between the Barclays Center and Dekalb Avenue stations at around 3:41 a.m.
Three MTA workers were on the train, none were injured. The minor derailment occurred during the regularly scheduled overnight subway shutdown.
The train has been re-railed and removed.
Service is currently running with extensive delays, but the MTA said it is aiming for a near normal afternoon commute.
B, D, N, Q and R trains are proceeding with extensive delays in both directions.
D and N trains run local between 36 St/ 59 St and Atlantic Av-Barclays Ctr.
Some northbound N trains will run along the Q line from Coney Island-Stillwell Av to DeKalb Av.
Some southbound Q trains will run along the R line from Canal St to DeKalb Av.
The MTA is advising passengers to consider using 2, 3, 4 or 5 train service between Manhattan and Brooklyn.
The cause of the derailment is not yet known, the FDNY is investigating.
