Starting Monday, two NYPD police officers will be on every overnight subway train as officials work to improve public safety.

The $77 million initiative will fund six months of overtime for more than 1,000 officers, including 300 cops on overnight subway patrols and 750 in stations and on platforms.

Turnstile “fins” may be coming to a subway station near you as part of the MTA’s push to stop fare evaders. The vertical, metal “fins,” as they’re called, have ridges on the top that are meant to deter fare evaders from jumping over the turnstile.
