 The branch extended from the terminus of the C&M's main line in Youngstown to the Ohio-Pennsylvania border.Completion of the C&M to Youngstown led to the significant diminution of traffic on the nearby Pennsylvania and Ohio Canal.Opened in 1840, the canal connected New Castle with Akron, Ohio, by following the Mahoning River and then West Branch of the Mahoning River before cutting cross-country to the city of Kent, Ohio.
