Straphangers may be surprised to see who’s riding the rails next week.
Police Commissioner Bill Bratton said Tuesday that he plans to tool around the subway to check up on quality-of-life issues such as homelessness.
Bratton, who once headed the Transit Bureau during his first tenure, said he sometimes takes the No. 4 or 6 trains to work at One Police Plaza.
He will take the late-night rides with buddy George Kelling, a criminologist.
“George and I are going to go out and ride the rails like old times for us, riding the rails and getting a sense, has the shelter-resistant population attempted to get back into any of these [subway] areas?” he added.
“We are going to resurvey the city, the parks, public places like Times Square to get a sense of … [because] we know what it looked like in the 1990s,” the city’s top cop said.
Homelessness in subway stations was up 13 percent last year compared to 2012.
