Notes
The LNER would often denote major modifications with a slash. E.g. B16/2 is a modified B16. Occasionally such modifications would be so substantial that a completely new class number would be given (eg. an A3 is a modified A1). Modifications of the same class typically share the same webpage.
Thompson and Peppercorn both reused class numbers. Reused class numbers are prefixed with the engineer's name.
