A man left his 1-year-old child in his car parked at the North Quincy Red Line station on Wednesday, officials said.
In a recording of a 911 call that the man made at about 8:30 a.m., he said he was heading back from the Charles/MGH Red Line station in downtown Boston to get his child.
"I left my 1-year-old baby in my SUV by accident this morning at North Quincy Station," the man said. "I'm on my way back to the station now."
The man said he left the baby at about 7:45 a.m. in the back seat of his car.
MBTA Transit Police and Quincy police and firefighters rescued the child. She was never in any distress, Transit Police spokesman Lieutenant Richard Sullivan said.
The man returned to the station, clearly distressed, about 20 minutes after the rescue, Quincy Police Captain John Dougan said.
"He was really upset that he had left the baby in the car," Dougan said, adding that this was an unusual occurrence.
"This is the first time I've seen someone leave a baby and get on a train," he said. "More often someone leaves a kid in the car for a quick run into a gas station or 7-Eleven."
The man's name is not being released as no criminal charges were filed.
