(WTNH) -- Metro-North's power problems could last several weeks. Trains are operating on very limited service, which will carry on into Thursday.
Plans are in the works for shuttle bus service, the MTA said Wednesday.
"For the remainder of today, Wednesday, September 25, 2013, extremely limited train service using diesel locomotives on the New Haven Line will remain in effect between Stamford and Grand Central Terminal due to the loss of Con Edison feeders that supply traction power to the NHL electric fleet," a post on the MTA's website said.
In a statement, Gov. Dannel Malloy urged riders "to seek alternate service and avoid taking the train today.. if at all possible."
The governor held a briefing at 4 p.m. to discuss the train situation.
At the briefing Malloy said, "We don't yet know how long it will take to restore service, but we are seeing estimates that could be as long as three weeks or more. Hopefully that is a worst case scenario and hopefully we'll soon have better information tomorrow or the next day."
Diesel-powered trains are making one trip an hour from Stamford to Grand Central, and one train per hour is leaving Grand Central at ten minutes after the hour to Stamford.
There is also limited service between New Haven and Stamford, with trains leaving at about 14 minutes after the hour.
Earlier in the morning all train service was halted from Stamford to GCT because of a power problem from a Con Ed feeder line near Mt. Vernon, New York. Thousand of commuters were stranded at stations along the line.
"They didn't know what was going to going on so they put us on buses. The bus half way to White Plains broke down, sat on the freeway for a half hour, another bus picked us up got us to White Plains, got into Grand Central about an hour and half later. It's been a fun day," said Brian Altadonna, a commuter.
"Con Edison is working at the scene to assess the extent of the damage and then determine the length of time to return power to the New Haven Line," the MTA said.
Riders are still advised to "seek alternate service and expect crowded conditions."
"Oh, I'll just have to make alternate plan time. As an American, roll up your sleeves and make plans," said Eli Ruiz, a commuter.
"I just had one appointment and I made it. I was a little bit late, but I left two hours early this morning. If I hadn't I would have really been in trouble," said Altadonna.
New Haven Line tickets are being honored on the Harlem Line, so customers who can make it to one of those stations can still take the train.
The power problem was also affecting Amtrak trains. Amtrak said via Twitter "Service New York Penn, NY (NYP) to New Haven, CT (NHV) delayed approximately 60 - 90 minutes due to power system problems."
