Furness Railway K2 - Numbering

Numbering

The first six of 1896 were numbered 21, 22, 34, 35, 36 and 37 by the Furness Railway (works numbers were 4174–4179). In 1900, two extra engines were added to the class, Furness Railway numbers 124–125. (works numbers 4651–4652). In 1913, two engines, FR Nos. 34 and 37, were fitted with experimental Phoenix smokebox superheaters, however, these were removed the following year. At some point in time locomotives 21, 22, 34 and 35 were renumbered 44–47 respectively.

By 1923 and the grouping of the FR into the London, Midland and Scottish Railway, all eight engines were still in service, and received LMS numbers, these being 10135–10142 (in order of their later numbers). They lasted until the late 1920s and early 1930s, performing secondary duties on the home turf, between Barrow-in-Furness and Whitehaven.
