A Williams Grove Railroad diesel trip departs the station, seen from aboard the Rockhill Trolley Museum Porto 172.
A partnership between the Williams Grove Historical Steam Engine Association, Inc, Middletown & Hummelstown Railroad, and the Rockhill Trolley Museum, has allowed Porto 172 to visit Williams Grove for their Annual Steam Festival. It was great to see so many happy faces and full trolley cars. It's amazing what a positive partnership between two rail organizations can accomplish!
