The Coventry to Leamington Line is a railway line linking the city of Coventry with the town of Leamington Spa. The line was opened in 1844 by the London and Birmingham Railway, initially only as far as Milverton. The line was extended to Leamington Spa Avenue in 1851. A connecting line to Berkswell opened in 1884.Late in the 19th century most of the route was doubled to increase capacity. Only a small section just outside Kenilworth, at Gibbet Hill, remained single track.
