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

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 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.
