After working the CSX interchange yard on the ex-B&O Indianapolis Subdivision on the east side of town, IERR 206 heads south on their former C&O trackage across the diamond in Cottage Grove, passing Milepost 45 and the old C&O milepost marker. MP 45 would've been measured from Cincinnati, but today the line ends at MP 18.9, near the southernmost active industry in Fernald, Ohio.
