An eastbound Long Island Rail Road train carrying nearly 1,000 passengers derailed in the East River Tunnel on Monday, delaying trains during the Monday evening and Tuesday morning rush hours.
A total of 35 out of 144 morning trains were canceled or diverted Tuesday, according to the MTA.

Two cars of a 10-car Hempstead-bound train derailed shortly after 6 p.m on Monday as it left Penn Station and entered the tunnel. No one was injured, and most passengers were led onto a rescue train.
The derailed train was removed from the tunnel early Tuesday morning, an MTA spokesman told CBS News. There is no word yet on how the afternoon commute will be affected.
The cause of the derailment is under investigation.
