The fiery blaze was captured on Citizen app.

Police say the train started in Flatbush before making its way to the 110th Street and Lenox Avenue subway station in Harlem, when the call came in about a fire on a northbound 2 train.

Train operator Garrett Goble, 36, rushed to evacuate the train, but did not make it out alive.

During Sunday’s daily COVID-19 update, Mayor Bill de Blasio praised the fallen MTA worker, saying in his last moments, he was saving others.

Goble was found on the train tracks, and was taken to Mt. Sinai Hospital.

A total of 16 others were injured in the fire.

Police say they are looking into three other fires that happened around the same time frame to see if they are connected.

No arrests have been made at this time.

The MTA tweeted out Friday in part that it is offering up to $50,000 for any information that leads to an arrest.

The NYPD is also offering a reward for any information leading up to an arrest,
