It was closed from 1 January 1917 to 1 February 1919 due to wartime economy,[1][2] and upon the grouping of the L&AR into the London, Midland and Scottish Railway (LMS) in 1923, the station was renamed Ardrossan Montgomerie Pier on 2 June 1924.
[1] The name change was to avoid confusion with the nearby G&SWR station of the same name, which was also incorporated into the LMS.
[4] Today Montgomerie Pier is the site of private flats overlooking the Ardrossan Marina, and no trace of the station remains.
The station consisted of two side platforms in an iron-framed wooden-clad building, and originally had a glazed roof supported on lattice girders.
[4] A booking office for boats to Belfast was situated at the pier end of the platforms.
