NEW YORK - New Yorkers once again faced a rough rail commute after track debris at a Manhattan subway station snarled the Thursday morning rush.

The Metropolitan Transportation Authority says the bulk of delays were on the 1, 2, 3, 4 and 5 lines.

The agency says debris on the tracks at 72nd Street were reported just after 7 a.m.

Southbound express 2/3 service resumed at 8:33 a.m.  

No injuries were reported and the incident is under investigation. 

Social media accounts show packed stations and stairwells on the affected lines.

Service changes and delays were also reported on northbound N, Q, R and W trains due to switch problems at Queensboro Plaza.
