Western Railway Museum, near Rio Vista California. They run excursions every weekend on old electric interurban rail-cars. They run on the old Sacramento Northern Railroad, which used to run from Chico to Oakland. Much of the old right of way in the east bay is now currently used by BART. This area however, pretty much looks as it did when these cars were in revenue service.
