The Cork and Kinsale Junction Railway (C&KJR) company built the first extension to the railway to the port of which opened in 1863 and was operated by the C&BR from the outset. The branch left the main line some from Cork at a station simply called and was notable for some long 1 in 76 and 1 in 80 gradients. The C&BR completed purchase of the line from the C&KJR on 1 January 1880. Due to mounting losses the branch was closed in on 1 August 1931 with the junction station being renamed Crossbarry.
