If anyone has any colour photos of these units I'd be glad to see them. I'm particularly interested in knowing more about:
(i) the pale yellow stripe (not the first class designator) which ran along above the windows; from memory I think it contained the text 'Rapid City Link Gatwick-London' but I'm not sure.
(ii) the blanked-out windows (e.g. the one behind the cab in the picture) where seats were removed to make space for luggage racks.
