The East Troy Railroad Museum is a 501(c)(3) nonprofit educational corporation with a mission to preserve the rail heritage of Wisconsin and America. We own, maintain and operate historic electric trolley and interurban railroad cars on track completed by The Milwaukee Electric Railway & Light Company (TMER&L) in 1907. Our rail line between Mukwonago and East Troy is the last remnant of The Milwaukee Electric Railway & Light (TMER&L) interurban rail system, which once operated over 200 miles of track in Southeastern Wisconsin.
