BRONX, N.Y. - The motorman who died in a bizarre subway fire in Manhattan last week has gotten an unorthodox memorial - his name spraypainted on the side of a train.

"Goble" - in honor of slain 36-year-old train operator Garrett Goble - was painted on a 3-by-18-foot piece on the side of a 4 train that pulled out of Woodlawn in the Bronx on Thursday shortly after 5:30 a.m., according to MTA reports.

The memorial reads: "Rest in Peace" and "Protect the Workers."

Goble, a father of two, died in an early-morning blaze on March 27 that erupted inside a northbound 2 train car in Harlem, at the 110th Street station, around 3:15 a.m.

Goble was found unconscious on the tracks in front of the train.

Transit workers are seeking a formal honor for Goble, launching a petition to rename the station where he died in his name. Transit workers say he helped two conductors on board get 16 passengers off the train.

"It is imperative that we keep his legacy alive for his family," the Change.org petition says.

A burnt shopping cart was found inside the charred train car.

Police are investigating it as a criminal case.

Nathaniel Avinger, 49, was questioned in the blaze as a person of interest, according to published reports.
