Liverpool and Manchester Railway

Stephenson had ascertained by experiments at Killingworth that half the power of the locomotive was consumed by a gradient as little as 1 in 260. He concluded that railways should be kept as level as possible. He used this knowledge while working on the Bolton and Leigh Railway, and the Liverpool and Manchester Railway (L&MR), executing a series of difficult cuttings, embankments and stone viaducts to level their routes. Defective surveying of the original route of the L&MR caused by hostility from some affected landowners meant Stephenson encountered difficulty during Parliamentary scrutiny of the original bill, especially under cross-examination by Edward Hall Alderson. The bill was rejected and a revised bill for a new alignment was submitted and passed in a subsequent session. The revised alignment presented the problem of crossing Chat Moss, an apparently bottomless peat bog, which Stephenson overcame by unusual means, effectively floating the line across it. The method he used was similar to that used by John Metcalf who constructed many miles of road across marshes in the Pennines, laying a foundation of heather and branches, which became bound together by the weight of the passing coaches, with a layer of stones on top.

As the L&MR approached completion in 1829, its directors arranged a competition to decide who would build its locomotives, and the Rainhill Trials were run in October 1829. Entries could weigh no more than six tons and had to travel along the track for a total distance of 60 miles (97 km). Stephenson's entry was Rocket, and its performance in winning the contest made it famous. George's son Robert had been working in South America from 1824 to 1827 and returned to run the Forth Street Works while George was in Liverpool overseeing the construction of the line. Robert was responsible for the detailed design of Rocket, although he was in constant postal communication with his father, who made many suggestions. One significant innovation, suggested by Henry Booth, treasurer of the L&MR, was the use of a fire-tube boiler, invented by French engineer Marc Seguin that gave improved heat exchange.

The opening ceremony of the L&MR, on 15 September 1830, drew luminaries from the government and industry, including the Prime Minister, the Duke of Wellington. The day started with a procession of eight trains setting out from Liverpool. The parade was led by Northumbrian driven by George Stephenson, and included Phoenix driven by his son Robert, North Star driven by his brother Robert and Rocket driven by assistant engineer Joseph Locke. The day was marred by the death of William Huskisson, the Member of Parliament for Liverpool, who was struck by Rocket. Stephenson evacuated the injured Huskisson to Eccles with a train, but he died from his injuries. Despite the tragedy, the railway was a resounding success. Stephenson became famous, and was offered the position of chief engineer for a wide variety of other railways.
