The Cork and Bandon Railway was formed by the '''''' (
8 & 9 Vict. c. cxxii) and began operations on the from
Bandon to
Ballinhassig from 1 August 1849, 25 seat horse omnibuses being used for transfers to and from Cork City. The section from Ballinhassig to Cork opened to public services on 1 December 1851. The was financially challenged after by building the Bandon to Cork section which had some costly overruns and future extensions to the network were undertaken by independent companies some of which operated their own services for a number years.
Extensions to the railway The Cork and Kinsale Junction Railway (C&KJR) company built the first extension to the railway to the port of . It was authorised by the '''''' (
22 Vict. c. xxiii), opened in 1863, and was operated by the 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 completed purchase of the line from the on 1 January 1880. The West Cork Railway (WCR) was formed by the '
(23 & 24 Vict. c. cciii) with the intention of extending the line to Skibbereen, the being in favour of such an extension but without the ability to raise the capital itself. The opened the section from Bandon to in June 1866 and operated the section itself hiring in rolling stock and locomotives from elsewhere. There were ongoing tensions between the and especially at with independent stations and goods transfer disputes. The itself was unable to resource the building of the Dunmanway to Skibbereen section which was completed by the Ilen Valley Railway (IVR) opening in 1877. Following arbitration, the section was worked by the . The operating situation agreed to was resolved on 1 January 1880 by running the network under a single operational management, the leasing the until absorbing it in the ' (
9 Edw. 7. c. xxxii) whilst concluding terms to absorb the in October 1882. 12 May 1866 saw the opening of the independently operated
Cork and Macroom Direct Railway (C&MDR) which initially used the terminus before almost immediately branching off on a line to . Toll charges and sharing difficulties led to to use its own newly built terminus at from 27 September 1879 with the connection severed soon thereafter. The completed an branch from to
Bantry which it leased to the to operate from 1 July 1881. In 1886 Skibbereen became an interchange with the
narrow gauge Schull and Skibbereen Railway. The (from Clonakilty Junction), , authorised by '''''' (
44 & 45 Vict. c. ccxvi), opened on 24 August 1886 and was operated by the . A long siding for a flour mill owned by the Bennett family at
Shannonvale about north of
Clonakilty was notable for being horse-operated. The siding was created in 1887 and extended to the mill shortly thereafter and remained horse operated until closure in 1961. Horse traction was used uphill, and trains were worked by gravity downhill. On 21 September 1887 a draft bill was submitted to the company's board. The draft would give the powers to construct a line to avoid Gogginshill Tunnel, at an estimated cost of £10,702. Other powers to be granted included a connecting line to the
Cork, Blackrock and Passage Railway, extensions to Cork's quays, and closure of the Gas Works level crossing.
Cork Corporation objected to the quay line and level crossing closure, and the connection to the Cork, Blackrock and Passage was defeated. The '''''' (
51 & 52 Vict. c. lxxxvii) passed on 5 July, changing the name of the to the Cork, Bandon and South Coast Railway (CB&SCR). Powers to build the line avoiding Gogginshill Tunnel were granted in this act of Parliament, but the line was never built. The
Timoleague and Courtmacsherry Railway opened and operated as a independent branch from on the branch with stations at , and terminated at the seaside village at . 22 October 1892 saw the opening of an extension of the Bantry branch by by another company, the Bantry Extension Railway, through to the pier at Bantry Bay, the again leasing the line. Direct passenger services onto the pier were introduced in 1908 to connect with Bantry Bay
steamers. These services ceased in 1936 and the pier was dismantled in 1949. An extension from to by the was operated by the from May 1893.
Baltimore was a port on the southernmost extent of Ireland and increased the length of the to . 1 January 1912 saw
Cork City Railways creating a connection between the and the rest of the Irish rail network by running a road tramway across the road bridges over the
River Lee from immediately before across to the
Great Southern and Western Railway at
Glanmire Road. The was subject to various damaging incidents during the 1922—1923
Irish Civil War, the most damaging to the railway being the partial destruction of the
Chetwynd Viaduct on 9 August 1922. Passenger services were restored between Cork and Bandon on 20 February 1923, with full service across the network being restored on 23 May.
GSR and CIÉ years The ,
Great Southern and Western Railway, and
Midland Great Western Railway were amalgamated into the
Great Southern Railway (GSR) in 1924. It then amalgamated with the
Dublin and South Eastern Railway to form the
Great Southern Railways in 1925, absorbing the smaller railways within the
Irish Free State. An early action of the new combined management was to re-instate the connection between the former and railways so the line from could use the terminus at to achieve some operating economies. Due to mounting losses the Kinsale branch was closed on 31 August 1931. A parliamentary question asked in February 1934 sought to prevent the line from being lifted, but the relevant minister lacked the power to do so. The line was fully lifted that summer. The junction station remained open, being renamed Crossbarry in October 1936. The was consolidated into
Córas Iompair Éireann in 1945. introduced
AEC railcars to the railway in 1954.
Closure Due to economic problems, competition from road traffic and falling passenger numbers, the line closed on 1 April 1961. The planned closure of the railway network met with strong local opposition, including the establishment of the West Cork Railways Association. At a meeting of Cork County Council's Southern Committee on 3 October 1960, councillors were very critical of 's running of the line. A report published by a local pressure group in 2022 suggested that the railway in West Cork could feasibly return. This suggestion was rejected by Minister for Transport
Eamon Ryan. ==Route==
