An MTA train operator who was killed in an arson attack was honored Monday at the subway station closest to his childhood home.

Interim MTA President Sarah Feinberg says March 27 was one of the darkest days in MTA history. That's the day 36-year-old Garrett Goble lost his life while operating the No. 2 train in Harlem.

Police say firefighters responded to a fire at the Lenox Avenue and 110th Street station and found the resident on the roadbed, where he was pronounced dead.

The NYPD arrested 50-year-old Nathaniel Avinger last Friday in connection with Goble's death. Avinger is charged with murder.

Goble's family and his two sons are relieved that someone is in custody.

The MTA honored Goble with a plaque and extensive artwork at the Flatbush Avenue station. Officials are asking people to submit their artwork and ideas for his memorial.

The Transit Workers Union also created a scholarship in Goble's name that will be given to students who need financial help.
