Porter is based on a H.K. Porter 0-6-0ST, built in Butler, Pennsylvania, north of Pittsburgh. These mainly worked in the dockyards on the east coast of the United States. The Brooklyn Eastern District Terminal Railroad, which served the dockyards in Brooklyn, New York, owned several examples of Porter's design.
Porter is painted viridian with yellow stripes and lining and a gold nameplate with black lettering. He has a gold star on each side of his lamp.
