The 2.5-mile (4.0 km) line started from the B&LR's terminus in Westleigh and crossed the Leeds and Liverpool Canal before heading south towards Kenyon.
John Hargreaves, an established carrier in Bolton leased the running rights over the K&LJR and the L&MR using his own engines and rolling stock until 31 December 1845.
The southern end of the B&LR was near the north bank of the Leigh branch of the Leeds and Liverpool Canal where it had transhipment facilities.
[4] In 1829 the company received royal assent to the Kenyon and Leigh Junction Railway Act 1829 (10 Geo.
4. c. xxxvi) authorising it to build a single-track line from the end of the Bolton and Leigh Railway near Twiss (now Twist) Lane in Westleigh to Kenyon, where a junction would be made with the L&MR which was at an advanced stage of construction.
[9] The line of the railway was surveyed by Robert Stephenson and the engineer in charge was either Charles Vignoles or John Rastrick.
[15][16] The link in the Manchester direction was closed by the time the 1849 Ordnance Survey map was published.
[20] Passenger trains began running the 28.5 miles (45.9 km) from Bolton to Liverpool on 13 June 1831.
[22] In 1834 the B&LR leased the running of the railway to John Hargreaves, an established carrier of Bolton.
[20] Hargreaves became a pioneer of excursions by rail, running Sunday trips from Bolton to Liverpool as early as 1841.
[b][28][29] The following year on 16 July 1846 the GJR was amalgamated with others into the London and North Western Railway (L&NWR).
[37] Regular passenger services on the line between Bolton and Kenyon ended on 29 March 1954 but wakes week traffic to North Wales continued until 1958.
