Bronx commuters faced unexpected delays last night after a southbound 4 train experienced a mechanical failure, causing the third and fourth cars to decouple while in transit before 6 p.m. Authorities confirmed that no injuries were reported following the incident, according to Gothamist.

The unexpected separation near East 149th Street and Grand Concourse caused service between the Bronx and Manhattan to be suspended for several hours. The FDNY responded with 60 fire and emergency medical personnel and had the situation under control within an hour, according to the report. Although service interruptions persisted overnight, normal operations were restored in time for the morning rush hour.

Metro Transit Authority (MTA) officials, continuing to investigate the cause of the uncoupling, successfully evacuated up to 60 passengers who were stranded between stations. In an interview obtained by NY1, a conductor present at the scene recounted the evacuation carried out by first responders.

Downtown 4 and 5 train riders faced service interruptions, prompting many to find alternative routes. One passenger affected by the delays told NY1 that they had to seek different ways home during the evening commute. NYPD officers were present at the station to provide assistance, while firefighters and MTA staff helped passengers safely exit the train, with the FDNY coordinating the response.

The MTA also pledged to continue investigating the incident to prevent similar potentially hazardous situations in the future.
