Multiple trains were rerouted due to flooding on the tracks at the 59th Street-Columbus Circle station Monday morning, the MTA said.
The flooding was caused by a problem in a building on street level, beginning around 7:10 a.m., the MTA said. It was unclear exactly what the problem was.
The MTA said personnel were at the station pumping out the water.
Most train service resumed around 10:15 a.m., the MTA said. B trains were not running between 145th Street and Brighton Beach until around 12:30 p.m.
The MTA said there may still be residual delays on the A, B, C, D, E, F, M and R trains.
