NEW YORK - New York City transit officials say a subway operator and conductor have been taken out of service while they investigate how a train ended up going the wrong way.
Officials say the uptown "A'' train pulled out of the Canal Street hub onto downtown tracks on Aug. 11.
The crew apparently did not hear a dispatcher's radio warning.
The operator stopped after seeing another train's headlights at West 4th Street. The Metropolitan Transportation Authority says there was no danger because the oncoming train had been halted.
The MTA says there had been signal problems, and the operator had been told to back up and switch to the other track. Instead, she kept going.
The MTA said a wrong-way train is "extremely uncommon."
Meanwhile, the "N" train continues to have a bedbug problem, according to CBS New York.
A conductor reported she was bitten on a Coney Island-bound "N" train Monday afternoon, according to the Metropolitan Transportation Authority.
She requested medical attention and was taken to Brooklyn Hospital Center, the MTA said.
That train was removed from service, and exterminators were immediately notified, the MTA said.
Bedbugs have been found on at least four more subway trains this month alone, three of them N Trains.
