The MTA is trying something new to deter fare evaders just weeks after installing spikes on some subway turnstiles.

The MTA estimates it loses around $285 million a year to fare evasion in the subway system — due both to turnstile jumping and to scofflaws entering thorough the emergency fire exit gates.

I do understand why they did it that way because it’s probably inexpensive for them,” a rider said. “It’s just adding a small piece instead of changing the entire design.”

The MTA has installed crescent-shaped metal shields to some subway turnstiles adding a few inches of height to the fare gate. Will it be enough to stop people from jumping over them? FOX 5 NY's Teresa Priolo takes a look at how things are working so far.
