A blind man walking with his seeing-eye dog slipped and fell onto the northbound A train tracks at West Harlem's 125th Street station Tuesday morning, police said.

The man, whose identity was not immediately released, was walking on the platform when he fell onto the tracks of the station near Saint Nicholas Avenue about 9:30 a.m., police and FDNY officials said.

He was rushed to St. Luke's Hospital, police said. His injuries were not expected to be life-threatening.

Witnesses said the man was walking with his dog when he fell, just as a train came into the station.

"Just witnessed an old man slipping and falling with his dog on the train tracks," Twitter user @ashley7th wrote just before 10 a.m. Tuesday, "luckily, the dog and the old man survived. please be careful."

Following the incident, A and D trains were running local between Columbus Circle and 145th Street, the MTA said.

B trains were not running between 145th Street and Brighton Beach, according to the transit agency's website.
