The Pennsylvania Railroad's Class 8-28d was a Mogul-type steam locomotive, designated by its 2-6-0 wheel arrangement. Built in the late 19th century, this class was a transitional design that improved tractive effort while maintaining a compact size. 

The 8-28d Moguls were efficient locomotives for branch line and local freight service. Their light axle loading and strong pulling power suited them well for secondary trackage and less-than-carload freight. Engine No. 20’s fuel supply evolved from wood to coal and then, around 1911, to oil. Although the lack of a trailing truck limited firebox size and steaming capacity compared to newer models, their reliable design enabled a long service life. As train weights increased and more powerful engines became available, the 8-28d class was phased out by the early 20th century but remained useful in yard and light-duty roles.
