BROOKLYN — A rail problem in the DeKalb Avenue station caused widespread service disruptions on the M, N, Q and R trains during Thursday's morning commute, officials and riders said.
Some portions of the routes were suspended while other trains terminated early or were rerouted onto other lines, the MTA said.
The MTA's website said the disruptions were caused by a "rail condition" but an authority spokesman couldn't provide more specific details about the problem.
Regular service resumed by 9:30 a.m., according to the MTA's website.
"Horrible delays on N, R, and D trains," tweeted Rosanna Lew about 9 a.m.
"@MTA complete fail on the N line this AM. No announcements in the station about service suspension. Passengers had to ask train conductors," tweeted @radmadmartigan about 9 a.m.
"Major train delays on manhattan bound n q and b trains from brooklyn #wooooo," tweeted Baily Newman about 8:30 a.m.
