Two MTA supervisors have been suspended over Tuesday's subway derailment in Harlem, a collision that forced hundreds of panicked riders to flee through darkened tunnels and crippled the transit system for the day.
The development comes hours after MTA officials said the derailment outside the 125th Street station was caused by human error -- specifically an "improperly secured piece of replacement rail" that was stored on the tracks.
Beth DeFalco, an MTA spokeswoman, said in a statement that the two supervisors who had been suspended were responsible for overseeing the track work. They are suspended without pay pending a formal review process.
