There was no immediate word on injuries

Service on the B subway line is suspended and Q trains are being rerouted because of a rail condition in Brooklyn, the MTA said Friday.

The agency initially reported the situation as a "derailment," but later referred to the issue as a "rail condition" at Brighton Beach. It's not clear what happened, but as of 9:30 a.m., the B line was shut down and southbound Q trains were running on the N line from Atlantic Avenue to Coney Island.

There was no immediate word on possible injuries. Chopper 4 over the scene showed personnel in reflective vests standing in the tracks around two cars of a stalled subway train. 

It comes less than a month after 34 people were injured when an A train derailed near the 125th Street station in Harlem. In that case, terrified riders were stranded in darkened, smoke-filled cars for two hours in some cases. The MTA said that derailment was caused by an improperly secured rail. Two supervisors have been suspended. 

While Gov. Cuomo predicted a "summer of hell" for NJ Transit and Long Island Rail Road workers amid Amtrak's months-long overhaul of Penn Station, city subway riders have thus far been subjected to a worse predicament. The 112-year-old system has been plagued by a series of signal problems, mechanical breakdowns and now possibly two derailments in the last few months. 

The second week of Amtrak's Penn overhaul has been marked by constant delays on almost every mode of mass transit in the tri-state area -- and almost none of the issues have to do with the infrastructure work at the Manhattan hub. There's plenty of blame to go around -- manpower shortages, signal problems, stalled trains -- but to commuters trying to get to work on time in a heat wave, the cause doesn't matter as much as the effect.

Among Friday's woes as of 8:30 a.m.:

Metro-North

  • The Danbury Branch has 30-minute delays due to a switch problem.

LIRR

  • A Port Jefferson to Long Island City train was delayed west of Jamaica and then cancelled due to equipment trouble.

NJ Transit

  • At least three trains left Hoboken late Friday morning due to what NJT called "operational issues." Two New York Penn Station departures were also delayed for the same reason, and one from South Orange. 
  • Four trains from various points were delayed due to mechanical problems.
  • One bus was delayed and another cancelled due to mechanical issues, while a third bus was cancelled due to operational issues.

Subway

  • Both the 6 and F lines were delayed running northnbound due to signal problems, while the F and M southbound also had delays because of signal issues.
