Queens subway commuters can't catch a break.

Service on the N, Q and R lines has been restored in both directions between 57th St.-7th Ave. and Queensboro Plaza, after a "smoke condition" led to hourslong delays during Tuesday morning's commute, the MTA said. Service was out about 9:32 a.m. and restored by 11:41 a.m.

Residual delays were expected on all lines.

The N and Q trains were suspended, while the northbound R train was running along the F line, due to the "smoke condition" at Lexington Ave-59th St., according to the MTA.

Meanwhile, the F train was experiencing delays due to an unrelated track fire north of the Van Wyck station in Queens, first reported just before 9 am. Northbound F trains were running express between Forest Hills and Parsons Boulevard. The E train was restored by 11 a.m., the MTA said.

The dangerous icy conditions also caused problems Tuesday morning. Due to icy conditions on the outside portions of the B train between Brighton Beach and Prospect Park in Brooklyn, the B train ran local in both directions this morning. The 7 train continued to run local after Monday's disastrous shutdown.

There were also some signal problems reported Tuesday morning, but it was unclear if they were related to the weather.
