DispositionAll scrapped

The LNWR Samson Class was a class of ninety 2-4-0 steam locomotives [1] built by the London and North Western Railway at their Crewe Works between 1863 and 1879.

Contents

They were officially designated "Curved Link 6-ft Passenger" due to the use of Stephenson valve gear which included a curved expansion link between the fore and back eccentric rods (earlier LNWR designs had used the Allan valve gear which had a straight expansion link) and the use of 6-foot (1.829 m) diameter wheel centres, which, together with 1+12-inch (38 mm) thick tyres gave a driving wheel diameter of 6 feet 3 inches (1.905 m). [2]

Ostensibly a mixed traffic design, they were the first locomotives with coupled driving wheels to be allocated for passenger duties on the LNWR.

History

They were designed by John Ramsbottom who had fifty built, all without cabs and with pierced driving wheel splashers. Ramsbottom's successor F. W. Webb, built forty more, all with cabs. The earlier locomotives also gained cabs, and all eventually had their splashers filled in.

All ninety locomotives were 'renewed' (replaced) by a like number of Waterloo Class locomotives between 1889 and 1905, but only eighty were scrapped quickly. The ten exceptions were transferred to the Civil Engineer's list, and these were withdrawn between 1914 and 1925. [3] No examples have been preserved.

In railway engineering, the term tractive effort describes the pulling or pushing capability of a locomotive. The published tractive force value for any vehicle may be theoretical—that is, calculated from known or implied mechanical properties—or obtained via testing under controlled conditions. The discussion herein covers the term's usage in mechanical applications in which the final stage of the power transmission system is one or more wheels in frictional contact with a railroad track.
