LNER K4 Class

Welcome to scot-rail.co.uk, Scotland's online railway community. The group is for any rail enthusiast interested in the railways and trains of Scotland. It not only consists of the wiki that you're reading now, but a busy online forum and mailing list, which was accessible to registered users. From April 2024 the forum has closed, with a replacement started on Groups.io.
The LNER class K4 were 3-cyclinder steam locomotives with a 2-6-0 wheel arrangement, designed by Sir Nigel Gresley for use on the West Highland Line. Six Locos were built 1937-1939.
