History
On 1 May 1848 Holywell Junction station opened as Holywell and until the early 20th century was the nearest station to the town of Holywell. In 1912 the London and North Western Railway constructed the branch line with a 1 in 27 gradient from Holywell Junction to Holywell Town. The line passed to British Railways (Western Region) in 1948. Although the line was well used, it was closed to passengers in 1954 and to goods in 1957. Holywell Junction closed to passengers in February 1966.
