Bolton & Leigh Railway

The Bolton and Leigh Railway was a 7-mile Lancashire railway opened in stages from August 1828, engineered by George Stephenson and one of the earliest steam-operated passenger railways in northern England. Running between Bolton and Leigh through the industrial landscape of south-east Lancashire, it predated the celebrated Liverpool and Manchester Railway by two years and formed part of the world's first interconnected network of steam railways.

The line's opening locomotive, Lancashire Witch, was built in 1828 by Robert Stephenson and Company at their Newcastle works — one of the most advanced locomotives of its era, incorporating the twin-cylinder arrangement and flanged wheels on rails that would become standard. When the Liverpool and Manchester Railway opened in 1830, the Bolton and Leigh extended its line southward to Kenyon Junction to connect with it, creating an early example of through-running between separate railways and establishing the principle of interchange that would eventually bind Britain's railways into a national network.

The Bolton and Leigh was absorbed into the Grand Junction Railway in 1846 and its route ultimately became part of the London and North Western Railway system. The line through Atherton and Leigh remains in use today as part of the Network Rail route between Manchester and Wigan, carrying passenger services on the same alignment that Stephenson surveyed almost two centuries ago — one of the oldest continuously-used railway routes in the world.
