The disruption happened about 7:00 a.m., on the first full day of use by commuters. Service on the 7 line halted at Times Square and passengers were told that they could take a bus further west.
Trains were not running to the new station for about a half an hour and reopened at 7:20 a.m., due to an issue with a track circuit, MTA spokesman Kevin Ortiz said.
7 train rider Sofia Feldman, 56, from the Upper West Side said it was a "fabulous idea" to have a stop on the west side but they should have ironed out the glitches before opening.
"They need to work the kinks out," she said. "They should've done a soft opening before the grand opening. You can't have delays during rush hour the first week."
Other straphangers Wednesday morning rationalized the troubles at the new station.
"It'd be great if it was working perfectly, but it's growing pains," Bryan Childs, 35, from Kensington. "The MTA could do a lot to improve. The first day, the escalator was down. It can be stressful to get to work."
The 34th Street-Hudson Yards station opened on Sunday after months of delays. It's the first station to open since 1989, according to the MTA.
EDITOR'S NOTE: The station was not closed as previously reported.
