A 2012 view of the old granite block paved roadway between the Indiana & Ohio Oasis, former Pennsylvania/Little Miami Railroad line and Walworth Avenue in Columbia-Tusculum, looking west from Delta Avenue. Note the curbs marking the edge of the granite paving. Between that curb to the left and the concrete retaining wall was one track, and where the cars are parked and the dumpsters are sitting was another Track. The large concrete bumper stops prevented any railcars from accidentally overshooting the end of track and rolling onto Delta Avenue.
