A series of issues -- from signal problems to FDNY activity to investigations -- caused headaches for subway and Metro-North riders Thursday.
FDNY activity at Columbus Circle caused delays on A, B, C and D trains. Northbound A trains were running local for a time as riders at the Columbus Circle station tweeted they smelled a strong smoke odor. Service was back by 8:30 a.m.
Separately, an investigation at Saratoga Avenue forced a total suspension of the 3 line between New Lots Avenue and Crown Heights-Utica Avenue before 8 a.m. Service was back by 8:30 a.m., the MTA warned of delays on the 3 and 4 lines.
