The CACV was used during the 1980s to store large numbers of idle St. Lawrence Railroad boxcars. Several of these cars were stored on Clintonville Hill in the vicinity of milepost 7, secured only with handbrakes despite the steepness of the grade. Vandals released the brakes on several cars, which rolled southward and derailed at the foot of the grade. Metal pieces from the wreck can be found between the railroad right of way and the west bank of the Susquehanna River.
