Hi everyone, this Super Rare piece is one of only five Custom Painted, decals, and lights by Overland custom painters as D&RGW SD39 (Super Duty) road #5325 , OMI #6242.1 and released by Overland 1998. This piece is a replica of the prototype featured in a movie called “Switchback” released in late 1997. There are only five of these in the entire world! This one is in excellent working condition, it test ran excellent in forward and reverse with all lights working. All lights are ‘grain of wheat’ light bulbs including the red warning lights which works prototypical as real locomotives do, where as the locomotive moves forward the reverse red light comes on and stays on, and when the locomotive is traveling in reverse and the forward red light comes on and stays on. In my opinion these types of light bulbs look more realistic than LED. This piece is one of my all time personal favorites.
