The Cardinal Greenway (TGC) is a multi-use recreational network combining a rail trail and an on-street route that together cross 62 miles (100 km) and five counties — in east central Indiana. The greenway, which was designated a National Recreation Trail in June 2003 and in 2018 was named to the Rails-to-Trails Conservancy's "Rail Trail Hall of Fame." uses the former CSX railroad track between Richmond and Marion. It is named after the Cardinal, the last regular passenger train service on the (Chicago-Cincinnati-Washington) route. Currently it is Indiana's longest rail trail project.
