The dreaded "signal problems" wreaked havoc on a commute for subway riders again Friday morning, with delays and service changes reported across at least three lines, and though those issues were cleared within about 90 minutes, more signal issues at multiple stations had emerged by afternoon.
The MTA first said at 7:30 a.m. signal problems at Forest Hills-71st Avenue in Queens, the same station where signal issues stymied riders a day earlier, were causing delays in both directions on the M and R lines.
Separately, signal problems at Cypress Avenue in the Bronx were causing delays on the No. 6 line.
Both issues had been fixed within about 90 minutes, but returned at Forest Hills shortly after noon, with delays reported on northbound E and F trains. Signal problems at other stations, from 25th Street in Brooklyn to 125th Street as well as Lincoln Center in Manhattan, delayed southbound R trains, northbound B and C trains and northbound No. 1 trains for a time early in the afternoon.
Rail riders also faced delays on Metro-North's Harlem line Friday. The MTA said southbound delays were reaching up to 25 minutes as of 8 a.m. because of a train with mechanical problems.
