...and the gateman came in different colors - also note the different color of the gateman's lantern.
What is also interesting is the sheet metal thickness - it's almost twice the thickness of its Lionel counterpart. You can't see it from this camera angle but the colored plastic in the hole in the base is green in the above example whereas it looks to be yellow in Dave's picture which means the color of the light coming from the base would match the color of the lantern it was illuminating.
