DARIEN -- A Metro-North commuter train slammed into a car on Camp Avenue Wednesday morning, injuring an elderly man.

The 92-year-old driver of the car was rescued by emergency personnel and bystanders at the scene and rushed away by ambulance. The extent of the man's injuries was not immediately known, but a witness said the man was alert when taken into the ambulance at about 10:25 a.m.

"I didn't expect to see the man conscious in the car," said Scott Perna, a Norwalk resident, who was waiting three cars back for the train to pass. "That was quite relieving."

The man's car was apparently infringing on the tracks when the 9:36 a.m. train from New Canaan was passing by Camp Avenue and struck the front end of the car. The collision turned the car around and pushed it into the station holding the railroad crossing gate.

David Fannon, a New Canaan resident who was on the train, said he felt nothing in terms of impact.

"We stopped at the cemetery, which seemed like a funny place to stop, and the conductor had just entered our car," he said. "There was a stopped truck next to the (train crossing) and I asked the conductor, `Is (the gate) supposed to be down?' and he said no, and left the car."

As Fannon got a closer look, he saw the car involved in the accident.

"There appeared to be an older gentleman in the driver's seat," he said. "He appeared OK, but shaken."

Fannon said the MTA crew handled the situation as "seamlessly as an incident like this could be."

Metro-North spokeswoman Marjorie Anders said there were no reports of any injuries on the train. Train service is suspended on the New Canaan Branch between Glenbrook and Springdale, with bus service being provided. The nearly 50 passengers on the train that struck the car began getting off the train just after 10:30.

Traffic in the area of Camp Avenue and Hoyt Street is backed up in both directions.
