EMD SD7 w/Sound & DCC - Paragon3(TM) -- Union Pacific #778 (Armour Yellow, gray, Road of the Streamliners Slogan)

This Broadway Limited HO Scale EMD SD7 Paragon3 diesel locomotive is based on six-axle units introduced in February 1952 and produced through November 1953. The SD7 was the 1500hp big brother to the GP7. Riding on six axles, three-motor trucks, they were designed to offer more starting tractive effort in road service than the GP7. EMDs introduction of an A1A freight locomotive led them to design the SD7 from the ground up. In appearance, they are very similar to the GP7 only with a longer hood. The radiators are grouped together at the end of the long hood and not separated as was seen on the GP7. The grill assembly protrudes from the side of the hood whereas with the GP7 the grills are fit flush with the hood. As built, the SD7 very closely resembles the SD9 with the visual spotting features being the boarding steps and a variation of the classification lights. The SD7 (SD for Special Duty) at the time was a massive locomotive at 60 feet 8 inches from coupler to coupler and weighing 3
