John Betjeman's 1952 essay "London Railway Stations" contains the following:
'The only time the Great Western went in for Classic in a big way was when it employed Philip Charles Hardwick to design the Paddington Hotel in the 'sixties. The dining room with its curving caryatids, probably by John Thomas, was almost up to the standard of Euston's Graeco-Roman office buildings. Just before the Hitler war this dining room, or "Coffee Room" as it was called, was ruined by being streamlined with plywood in a jazz-modern manner, so that it is now like any semi-smart new restaurant...
'... There was an unfortunate period in the nineteen-thirties when the Great-Western went "Modern" in the Great West Road sense of the word, with its new office buildings at Paddington. It adopted at this time too that hideous monogram on its engines. When Paddington Station was rebuilt the company employed Digby Wyatt on architectural effects.'
