NEW YORK - The Metropolitan Transportation Authority is facing its first lawsuit over Tuesday's A train derailment in Harlem.
Attorney Sanford Rubenstein says a rider named Sheena Tucker filed a notice of claim for $5 million in damages.
Rubenstein says Tucker suffered a serious disk injury in the derailment.
Two MTA supervisors were suspended without pay over the incident.
The agency says the workers were in charge of a rail replacement project near the 125th Station where the train derailed.
Investigators say the derailment was caused by a piece of unsecured rail stored that was being stored next to the tracks.
Extra rail is often stored nearby to speed up repairs.
Former MTA Chairman Peter Kalikow says the agency needs to take the time to do proper maintenance, even if that means long-term shutdowns.
"If some service disruptions are necessary, they have to take it. It's not that this is a thing that was coming for a short time. It was coming for a long time," Kalikow said.
MTA officials say crews are now inspecting the entire subway system for any loose rail.
