The station was opened on 23 December 1940 jointly by the
Great Western Railway and the
London, Midland and Scottish Railway. The station served the
Shell Thornton Aero Engine Laboratory (AEL), which was responsible for developing fuels and oils for the aircraft of the
Royal Air Force. A short distance from the station was a signal box. This controlled all of the sidings used for freight. Shell stopped using rail as a method of transportation of goods, and subsequently, the
sidings were removed. Eventually, the signal box was dismantled and donated to the Embsay & Bolton Abbey Steam Railway. Today, the signals for this line and station are controlled at
Helsby and
Ellesmere Port signal boxes, operated by
Network Rail. The station was originally earmarked for closure under what is known today as the
Beeching Axe, a report created by Dr. Beeching entitled "The Reshaping of British Railways". This was a report commissioned by the government to find out how money could be saved, as use of the railways began to decline.
Quietest station in the UK Station usage statistics for 2004–05 showed 40 passengers using the station, less than one per week. Passenger numbers began to increase at the station in 2005–06, with 130 people using it in 2005–06. This rose sharply to 326 in 2006–07, despite the same rail services being operated. In January 2020 the station was named as the joint quietest in the UK, alongside
Denton Station in Greater Manchester, with just 46 entries and exits in the period 1 April 2018 to 31 March 2019. Passengers increased to 82 the following year, but Stanlow and Thornton remained one of only six British stations to serve fewer than 100 annual passengers. ==Facilities==
