A trash fire at 145th Street Monday morning caused the B and C subway lines to completely shut down and stopped A and D train service north of 125th Street, according to WNBC Monday.

An FDNY spokesperson reported that trash on the train tracks caught fire at about 7:25 a.m. The Metropolitan Transportation Authority shut down the A and C lines at first, but by 8:30 a.m., B trains became suspended in both directions and D trains stopped running north of 125th Street. The MTA decided certain northbound D trains would not run past 36th Street in Brooklyn, West Fourth Street or 34th Street in Manhattan. Riders from Brooklyn to Manhattan were inconvenienced during their morning commute.

Those who planned to take the A, B, C or D trains from 145th Street left the station to find alternate routes.

Twitter user Tamara Hansson tweeted, “Now me and several hundred other people are walking to the 145th 1 train.” She later added, “Literally a thousand people waiting at 1 train, and train just drove straight through — we are all gonna be late for work.”

The MTA evacuated several trains amid the smoke. Some trains turned off their power. The fire occurred the second week the MTA planned to conduct FASTRACK repairs on the A, C, B and D lines. Repairs are planned from 10:00 p.m. and 5:00 a.m. the week of July 17, 2017— no A trains will run between 59th Street and 168th Street, no D trains will run between 59th Street and 161st Street-Yankee Stadium and service on the B and C trains will end early each night.
