Police activity in Manhattan and a person killed by a train in Port Chester caused major delays for subway and Metro-North riders for Wednesday's commute.
An NYPD investigation at 33rd Street prompted sweeping changes on the Nos. 4, 5 and 6 lines shortly after 9 a.m. The nature of the probe wasn't clear, but the MTA said express 6 train service out of Parkchester was suspended for a time and 4 and 5 trains were subject to service changes.
The MTA said service had resumed with extensive delays by 9:45 a.m.

Riders were advised to expect delays on 2, 3, 4, 5 and 6 trains as authorities investigated. Earlier, a police investigation at 34th Street prompted delays on the 1, 2 and 3 lines; it wasn't clear if the situations were related.
Metro-North riders on the New Haven line also experienced major delays Wednesday. A person was struck and killed by a train at Port Chester, causing delays of up to 40 minutes for people who use that line.
Metro-North first noted the disruption at about 5:45 a.m.
By 8:30 a.m., customers reported sitting idle on trains for 30 minutes or more with little information. At 8:40 a.m., Metro-North said eastbound service had resumed from Rye, Port Chester and Greenwich, but delays remained.
It wasn't the only Metro-North line that had issues Wednesday. Service on the Danbury branch was delayed by nearly an hour because of a late connection.
