The Marshall Steam Museum is a collection of antique steam-powered cars on the grounds of Auburn Heights Preserve, a state park in Yorklyn, Delaware. T. Clarence Marshall was fascinated by the steam power that operated his family's mills. He became a licensed dealer for Stanley Motor Carriage Company and began acquiring a personal collection of steam automobiles. The collection was first opened to the public in the 1970s. Following its donation in 2008 by his son, Tom Marshall, the collection is owned by the nonprofit Friends of Auburn Heights Preserve, which operates the park in partnership with the state.
The collection is housed in the Auburn Heights carriage house, where a team of volunteers maintains the vehicles so that they remain fully operational. Included in the collection are 15 Stanley cars and several steam and electric cars from other manufacturers. The Museum's collection also includes a 1/8-size steam locomotive that runs on tracks around the estate called the Auburn Valley Railroad. Visitors are able to view the collection, and on certain days rides on the cars and trains are offered to the general public.
