Officials with Metro-North said the New Haven Line experienced delays because of power problems in the Bridgeport area on Thursday morning.
Officials said power was restored around 8 a.m.
Before then, customers traveling between New Haven and Stamford said they experienced delays. Metro-North officials said at least one train was disabled on the tracks as a result.
"The accident gives pause to who's watching out for us," said Bob Bruder of Fairfield. "Who's in control? I think that's pretty scary."
Delays of up to 10 minutes were reported at first, but Metro-North officials later said delays of 20 minutes were expected and passengers should listen to announcements at their stations.
Anyone riding the line Thursday morning saw crowded and combined trains.
This was the latest headache for rail riders.
In November, a train on the Hudson line derailed in the Bronx. Investigators said four people were killed.
A power failure in New York lasted 12 days in September, crippling the New Haven line.
In May, a rail worker was killed in West Haven while working on the tracks just 10 days after a train derailed and collided with another in Bridgeport. In that derailment, more than 70 people were injured, officials said.
"Try not to think about it," said Vanessa Bruder, a Fairfield resident, "because what are you going to do? We have to commute."
Officials did not expect the recent outage to affect the Thursday evening commute.
