A fire erupted on a work train Tuesday morning in the New York City subway, sending heavy smoke billowing through the Astor Place station and injuring a dozen people. The blaze caused significant disruptions to subway service in the area.

FDNY Assistant Chief Tom Currao reported that at least seven MTA subway workers and five firefighters sustained injuries. The injuries were primarily attributed to smoke inhalation, according to officials.

The incident occurred on a work train traveling through the station, located in Manhattan's East Village. As the fire broke out, a northbound train arrived at Astor Place and its passengers were safely discharged. Firefighters then assisted these passengers, ensuring none were harmed.

Commuters experienced delays on Brooklyn-bound 4 and 6 trains as a result of the incident. City officials had advised the public to expect disruptions, particularly impacting the morning commute.

MTA officials, in coordination with the Fire Department, aimed to clear the affected train and restore service as quickly as possible. Currao indicated that once the Fire Department gave the all-clear, the electrical unit train could be moved, facilitating the resumption of service, though residual delays were anticipated.

The Fire Department's presence was substantial, with fire trucks visible at the scene. The smoke was described as heavy, affecting both street level and the station platforms, necessitating a response from emergency services.

This incident highlights the potential hazards associated with subway operations, particularly involving work trains and electrical systems. The swift response from the FDNY and MTA personnel was crucial in managing the situation and preventing further injuries.

Further details regarding the cause of the fire were not immediately available, and an investigation into the incident is expected. The focus remained on clearing the tracks and resuming normal service for the city's commuters.
