The Harborne Branch Line opened in 1875, connecting New Street to the outlying suburb of Harborne. A connection to the LNWR was created at Monument Lane. The branch terminated at Harborne railway station. The line began to suffer from falling passenger numbers, largely due to the increasing popularity of buses but also due to train delays as a result of congestion of routes at New Street station. Icknield Port Road station closed in 1931, and the other stations closed to passengers on 26 November 1934. The last passenger train to run on the line was an enthusiasts' special on 3 June 1950. The line closed to freight traffic on 4 November 1963.
