Hi all.
Can anyone direct me to either a website or book that contains the proper list of power classifications used by British Railways? I'm thinking of the
4P, 4MT, 7F things, not the Type 1, Type 2, stuff.I've found a wiki that covers what the LMS did that the BR ones are based on. It mentions changes that BR made, but doesn't list, explain or provide a link to a source for what those changes were.
