The mark consists of the word "chugga" in lowercase soft blocked orange letters outlined in red. Below the lettering, there is a red steam engine with a black roof and black wheels raised off of white tracks, with an engineer's head and arm hanging out a window. The engineer has a white semi-circle smile on his tan face and is wearing a blue and white striped engineer's hat. His eyes are black crescents. His head and arm are outlined in black, except where the hat covers his head. There is a puff of white smoke coming out of the engine's smokestack and a white cloud in the background, with a blue sky. There is a yellow and black railroad crossing sign on one side of the tracks, just behind the train engine. The track is curved and appears to be on top of a green sloped hill, with brown rocks scattered along, above and on the opposite side of the tracks toward the back and behind the engine. The engine includes a black cow catcher, gray attachment ring in the rear, and a gray rod connecting the axles of the wheels.
