HO scale models were built by Clyde King and featured in his article in Mainline Modeler's July 1990 issue. The units are Athearn kits with several significant modifications to correctly represent Espee GP38-2s built in 1980. Note the round shotgun style exhaust stacks (scratchbuilt); nose and rear-end headlight packages (front bracket was scratchbuilt; rear is a Detail Associates bracket with DA parts affixed to it); among other items. Shells are attached to the frame with small screws, thus avoiding the "squeeze" necessary to remove the shell from the frame and possibly damage stanchions and/or other details. Fuel tanks have a wrapper placed around them to get the correct length and appearance. SP 4817 features the cab roof mounted icicle breaker bars, winterization covers over the inertial intake screens behind the cab, and an Emrex gyra headlight system circuit (no longer available) installed in the forward direction. Steps at the stepwells were scratchbuilt using a brass fixture Clyde fabricated (don't call it a jig!) to drill the small holes. These are no longer necessary as detail part manufacturers offer them in brass. Cab is a Cannon & Co. kit; the four-hole jacking pads were scratchbuilt as these pre-date availability of Cannon's part.
