Furness Railway class 1 (1870)

Although the Furness Railway had originally been built as a pure mineral railway, a considerable amount of passenger traffic developed over the years. In 1870, Richard Mason introduced the first class of locomotive solely designed for that role. These were of the 2-4-0 type, with drivers of six and a half feet and cylinders of 16 by 20 inches.

As the original class 1, built by Bury in 1844 was withdrawn in the same year, the first locomotive of the new type was also numbered 1. Rob Rush later designated them class E1 in his books. In 1891, seven were rebuilt into class J1 2-4-2T tank locomotives. The original 2-4-0 locomotives were withdrawn between 1907 and 1924 and only the last one briefly came to the LMS, receiving the number 10002.
