A southbound G train derailed around 700 feet north of Hoyt-Schermerhorn Sts. at around 10:35 p.m. last night. The FDNY reported three injuries, though none serious, and approximately 80 passengers — a fairly empty late-night train — had to be evacuated. The MTA has said that the front two wheels of the first car jumped the track.

As a result of the derailment, G train service will be limited with single-tracked service on the Queens-bound track only between Bedford-Nostrand and Court Sq. and “extremely limited” service between Fulton St. and Bedford Nostrand. The G is, in effect, now a shuttle. The MTA is urging riders to use the B38 along DeKalb or Lafayette Avenues as an alternate, and Transit is providing free transfer from the G at Fulton St. to the C at Lafayette Ave. and from the Broadway stop to Lorimer St. on the BMT’s J/M/Z lines. F service from Bergen St. south continues to operate normally.

The MTA is currently investigating the derailment, and while I have no basis for this conclusion, the incident follows a mid-afternoon rail condition near the same spot. According to MTA records, that issue had been cleared up a little after 5 p.m. on Thursday evening. More details to come.
