Transit crime made for a violent commute for several New Yorkers Tuesday.

According to police, a 45-year-old man was stabbed in the chest just before 3 a.m. at the 4 and 5 train station on East 138th Street and Grand Concourse.

Officers said they discovered the victim wounded on board a southbound 4 train. The victim was taken to a hospital and is expected to be OK.

Police said they have no description of the person who did this, leaving some people in the neighborhood even more concerned about safety than they normally are.

“I’ve never thought a stabbing would be around this neighborhood,” Andre Stuckey, who lives in the neighborhood, said.

Others in the area believe the Bronx train attack may have been an isolated incident.

“That was probably just part of some minor miscommunication,” local resident Jairo Diaz said.

The Bronx stabbing happened just hours after a stabbing at the 36th Street station in Queens.

Police said a man got into a dispute with a woman aboard an F train that escalated into a fight just before 1:30 a.m.

According to officials, the male suspect stabbed the female in the left shoulder before cops took him into custody. The woman was taken to a hospital and is expected to be OK.

Also on Tuesday, police said a man shoved an MTA worker on board a train at the 59th Street-Lexington Avenue station.

The 34-year-old worker’s hand was injured on a subway pole and police arrested the 45-year-old suspect, officials said.

While transit crime is down overall so far this year compared to last year, according to the latest figures from the NYPD, transit crime in the 40th Precinct, where the Bronx stabbing occurred, is up about 27% year to date.

“In the past couple of months it’s been increasing with the crime in the transit system,” Stuckey said.

According to police, a knife was found at the scene of the Queens subway stabbing and charges for the suspect in that incident are pending.
