UP was the original Transcontinental Railroad and was another railroad that painted its early piggyback trailers like its passenger locomotives. The trailers have a Harbor Mist Gray roof with red pinstripe separator between the roof and Armour Yellow body. Another red stripe separates the yellow from the gray lower body. Union Pacific is spelled out in red lettering and a UP shield with wings is on the front. The trailers also carried the slogan “Fast Pick Up and Delivery Service” in the lower red stripe.
