[3] Founded in October 1940, the museum is located in East Windsor, Connecticut and is open to the public April through December.

The museum operates a 1.5 mile (2.4 km) heritage railroad over the original right-of-way of the Hartford and Springfield Street Railway Company's Rockville Branch.

The line also serviced Piney Ridge, an amusement park located just between Broad Brook and East Windsor.

Most trolley companies built parks — like Piney Ridge — to create revenue on the one day no one went to work, Sunday.

Piney Ridge featured a large pipe organ, a dance floor on trolley springs, and a baseball field.
