In 1895, a new junction was created when the LNWR's single track line from Weedon to Daventry was extended westward to join the Rugby to Leamington line at Marton Junction, which was two miles southwest of Marton station in a deep cutting through a ridge of high ground.

At Leamington, the LNWR used a single track connection facing Rugby to exchange goods trains with the adjacent Great Western Railway.

[1] The local passenger service was withdrawn by British Railways in June 1959, and the local goods sidings were closed in the early 1960s, however the line continued to see use as a diversionary route by both passenger and freight trains until 1965, during the electrification of the West Coast Main Line.

[1] From Rugby, the general course of the line was southwest as far as Hunningham after which it swung west for the last five miles into Leamington.

For the first few miles out of Rugby the line was mainly routed in shallow cuttings but west of Birdingbury it crossed the River Leam on a low viaduct.

From there it ran across the flat open expanse of Marton Moor before cutting through high ground to follow the valley of the River Leam for the last few miles.

The trackbed from Draycote (southwest of the former Dunchurch station) to Birdingbury has been surfaced by Sustrans as part of National Cycle Network Route 41.

[2] The long straight stretch of trackbed from the A423 across Marton Moor to the cutting near Hunningham is mostly clear of undergrowth and is regularly used by walkers; however, there is no legal right of way and this section can be very muddy in winter.

Further west, a 1.5-mile (2.4 km) stretch of trackbed from the Fosse Way to the Grand Union Canal, titled 'Offchurch Greenway'[3] and also part of Route 41, is well surfaced and maintained, this is planned to be extended up to Birdingbury with construction originally scheduled to begin in summer 2021.
