The Furness Railway 21 class (classified "K2" by Bob Rush)[1] or "Larger Seagulls", were a class of eight English 4-4-0 steam locomotives designed by W. F. Pettigrew and built by Sharp, Stewart and Company of Glasgow for the Furness Railway.

They lasted until the late 1920s and early 1930s, performing secondary duties on former FR lines, between Barrow-in-Furness and Whitehaven.

[3] The Edwardian 4-4-0 type is a fairly common design pattern in British steam locomotives.

However Edward differs in having a cab with dual glazed side windows, a much more characteristic feature of North Eastern railway locomotives.

The tapered non-circular spectacle plate windows and the higher boiler line are distinctively those of the NER Class R1.
