San Francisco is not the only place to enjoy a ride on a trolley car. Check out the other side of the United States at Kennebuckport, Maine. The Seashore Trolley Museum in Portland was established in 1939 with only one open trolley car – old Number 31 from the Biddeford & Saco Railroad Company. From that simple beginning, the Museum now has a collection of over 250 mass transit vehicles, the majority of which are trolleys. These vehicles have been obtained from all over the United States, from Canada and other countries. The Seashore Trolley Museum boasts of being "the oldest and largest electric railway museum in the world".

The Museum is a non-profit, educational institution that operates as an entity of the New England Electric Railway Historical Society. The Museum displays a living history of public transportation and provides a facility for the collection, restoration, and preservation of related artifacts and information.
