A subway car derailed in Manhattan Tuesday morning, causing at least 3 minor injuries, authorities said.

The A train derailed near 125th Street along St. Nicholas Avenue at around 9:48AM.

FDNY is on the scene with a third alarm response and reporting that one train car derailed and all passengers have evacuated. Rescue units are conducting searches, with the current patient count at four – all with with minor injuries.  
 
The derailment caused a power outage affecting  the A/B/C/D line between 125th street and 145th Street, which caused some trains to be stuck in the tunnel with passengers aboard. 

“We were on the express track from 145th to 125th… All of a sudden it was like the train just started like banging against the walls of the tunnel,” one passenger told CBS2’s Emily Smith. “It was going up and down. It was sort of like a runaway roller coaster — like a bucking horse.”

Photos posted to social media show passengers walking along the tracks in a dark subway tunnel, using their phone flashlights as a guide. Firefighters are seen illuminating the way. The MTA urged stranded riders on other trains not to get off their subways and to wait for directions from crew.
