Wild scene on the 4 train yesterday — three subway cars detached mid-ride near 149th St–Grand Concourse in the Bronx. Thankfully no one was hurt, but service on the 4 and 5 lines was suspended for hours while the MTA investigated what they called an “extremely unusual mechanical failure” 🎥 @donjulio_223 | New Yorkers
