A decoupling of two train cars forced the suspension of service on a subway line running between Manhattan and the Bronx on Sunday evening, the Metropolitan Transportation Authority said.

Passengers were safely taken off a southbound 4 train near 149th Street after the third and fourth cars became detached, an MTA spokesperson confirmed. No injuries were reported and the investigation was ongoing, the spokesperson added.

The MTA announced the mechanical issue shortly after 6 p.m., saying it had suspended 4 and 5 train service between the Bronx and Manhattan. The service suspension was expected to continue into Monday morning, the spokesperson said.

During the suspension, the 4 train was running in two sections between Woodlawn and Burnside avenue stations in the Bronx and from the Crown Heights-Utica Ave. station in Brooklyn to 125th Street in Manhattan, the MTA said.  Service on the 5 train was limited to a small section of the Bronx between the Eastchester-Dyre Avenue station and the East 180th Street station.

Passengers were being told to use the 2 and D trains, or buses, for service between Manhattan and the Bronx.
