A subway train derailed near the West 8th Street-New York Aquarium station in Coney Island on Wednesday, causing extensive disruptions on the F and G lines, according to the Metropolitan Transportation Authority (MTA). The incident occurred around 12:20 p.m. as emergency teams worked to assist passengers onboard the train.

This derailment comes just six days after a collision and derailment on the Upper West Side, prompting National Transportation Safety Board Chair Jennifer Homendy to announce a comprehensive investigation into the entire subway system, including its management and supervision.

Photos obtained by Gothamist show the Manhattan-bound train breaking through a wooden barrier as it jumped the tracks. One of the cars landed precariously close to the edge of the line's elevated structure. The cause of the derailment is currently unknown, and the NYPD has referred inquiries to the MTA.

During a news conference, NYC Transit President Richard Davey stated that the train was traveling at a reduced speed through a construction zone when it derailed. Fortunately, all 32 passengers aboard were safely evacuated without any injuries.

Davey reassured subway users, saying, "Derailments do happen. They shouldn't, but they do from time to time. Customers should feel safe taking the subway." He also expressed his goal of restoring full service on the affected line by Thursday morning's rush hour.

Joseph Natoli, an accountant with a view of the tracks where the derailment occurred, stated that he did not immediately notice the issue. He described the train's speed as slow, suggesting that it was not a high-speed derailment.

Notably, the tracks in the area have undergone maintenance in recent months, according to Natoli. The city's emergency management agency reported that F trains were not running between Avenue X and Coney Island-Stillwell Avenue stations, citing activated brakes on one of the trains as the cause. G trains were operating with delays in both directions.

The previous derailment on the Upper West Side had disrupted service on the 1, 2, and 3 lines for over 48 hours. In that incident, two trains on the 1 line collided at a slow speed, causing them to jump the tracks. Approximately 300 passengers were involved, with about 25 sustaining minor injuries.

Following the recent derailment, NTSB Chair Jennifer Homendy expressed concern over the subway's safety and announced that the NTSB would welcome the opportunity to investigate the incident, should the need arise.

As investigations and repairs continue, commuters are advised to check for updates on service disruptions and delays.
