The Marshall Steam Museum is flocked by visitors because of it contains the largest operating collection of Stanley steam cars in the world. The building occupied by the Museum was built in 1947 by T. Clarence Marshall for the purpose of housing his continuously growing antique automobile collection.
The Marshall Steam Museum occupies over 6,000 square feet of exhibition space and aside from Marshall?s collection, visitors to the Museum will also get to view the displays of the Friends of Auburn Heights Preserve featuring a remarkable collection of operating antique automobiles dating back from 1901 to 1937. This collection includes a 1901 mobile, one white steam car that is currently on long-term loan to the Friends, an electric car and two 1930?s internal-combustion 12-cylinder Packards.

Visitors will also get to enrich their knowledge about the history of the Marshall family as well as the mill town within Yorklin through the other exhibits. Other features include small locomotives and model steam engines, antique music machines, and standard-gauge Lionel electric trains from the 1930s.

One of the latest features within the Museum today is the new hands-on exhibit illustrating the Stanley power plant functions and its operational processes.
