Prior to the building of Marion Union Station, Marion had a dilapidated passenger coach serving as a ticket station. Marion Union Station figured prominently during World War Two. Troops stopped here for canteen service. In 1923, the body of President Warren G. Harding was brought through the station to be taken to his father's home for the funeral. A non-profit group purchased the station just before the wrecking ball would have torn it down.
Restoration is about complete and the station serves as a railfan site for filming trains.
It is said to be one of the hot spots in the nation for photography. Other equipment includes a Baltimore and Ohio ALCO S-4 diesel, two cabooses and a railroad steam crane. On US Route 33. PRR 478062 caboose on display. Operates special event mainline excursions.
