[1] The scheme was revived in the 1880s by the London and North Western Railway (LNWR) the successor to the L&BR, who constructed the line in two phases.
Firstly, they obtained powers in 1885 to construct a four-mile (6 km) long branch to Daventry from Weedon, this was opened on 1 March 1888.
[2] Ownership of the line passed to the London, Midland and Scottish Railway (LMS) in 1923, and then British Rail in 1948.
Additional trains also ran in the mornings and afternoons between Leamington and Flecknoe (later cut back to Napton) for the benefit of schoolchildren.
The service was cut back sharply during World War II, and the pre-war timetable was never fully reintroduced.
A short section was retained between Marton Junction and Southam to serve the cement works, along with a stretch of the Rugby-Leamington line from Rugby.
