QUEENS — Trains on the N, Q and R lines resumed after they were suspended between Manhattan and Queens Tuesday morning because of a smoky track fire in one of the tunnels, the MTA said.
The fire erupted between Queensboro Plaza and 57th Street-Seventh Avenue about 10:20 a.m., an MTA spokeswoman said.
Firefighters brought the small blaze under control within 40 minutes, an FDNY spokesman said.
Investigators were still trying to figure out what sparked the fire, transit and FDNY officials said.
No injuries were reported.
Regular service resumed about 11:40 a.m., the MTA said.
The halt came amid headaches along the 7 line caused by ice on the third rail.
Trains along that line were running with limited service Tuesday after the entire service was knocked out Monday.
A separate track fire in Queens also knocked out service on the E and F lines Tuesday morning.
