New London — At the request of  Massachusetts authorities, and due to ongoing police activity, Amtrak Acela Express and Northeast Regional service remains suspended indefinitely in the Boston area.  Northeast Corridor trains are terminating at New York Penn Station.  

Amtrak Downeaster continues to operate a modified schedule with no service to Boston.

Amtrak service at Union Station in New London has been canceled as a result of the police search for the Boston Marathon bomb suspect in Boston.

Amtrak service is temporarily suspended between Boston and Providence, said Cliff Cole, a spokesman for Amtrak. He said Boston authorities asked them to suspend service at 5:45 a.m.

Cole said he could not provide information on when service would resume.

Amtrak service is operating normally between Washington, D.C., Philadelphia and New York. The Springfield Shuttle between New Haven, Conn. and Springfield, Mass. is also operating on a normal schedule.

Cole said an earlier incident of suspicious activity in South Norwalk has been cleared and found not to be connected to the Boston bombings.

"We've been cooperating with law enforcement and will leave it at that," said Cole.

According to a New York Times blog, a New York Metropolitan Transportation Authority Police official said video surveillance footage from the stations in Providence, New Haven and New London were being reviewed to make sure the suspect didn't get off at those stations.

Avis Smith was scheduled to go to Newport News, Va., to see her ailing son who is in the hospital, but was told that she would not be able to take the 7:45 a.m. train out of New London.

Smith, who also lives in Virginia, could not contain her tears as she headed back to a cab to take her back to her hotel in Groton. Her husband is doing some work at a local shipyard, she said.

Smith booked a ticket for the same time Saturday. "I hope he holds on," said Smith.

Debbie O'Connor, of Westerly, said she was told there to come to New London to catch a train, but discovered that service here was canceled as well.

O'Connor was headed to New York for work. She was told to go to Old Saybrook to attempt to get the 9:14 a.m. Shore Line East train that would take her to New Haven, where she could take the Metro North to Grand Central Station in New York.

"I may just drive to New Haven and leave my car there," said O'Connor. "I don't like driving to New York."
