A few hours ago, F train service was suspended between Avenue X and Church Avenue due to falling debris at an elevated subway station. WABC 7 reports, "The problem started around 5 a.m. this morning when a 4x8 piece of the platform became loose and collapsed down below at the 18th Avenue Station." The transit authority "took out the remainder of the loose concrete, while engineers examined the structural integrity of the platform." Manhattan-bound service resumed, but Coney Island-ound service is skipping 18th Avenue.
