Class 21 and 29
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.
Fifty-eight Type 2 Diesel-electric locomotives were built by NBL for British Railways, numbered D6100 to D6157.
