Not that I would expect anybody in the media to know that the West Coast Main Line was either on the west, near a coast or a railway line, even less to be aware of where the old lady originated and spent her working days on the opposite side of the country. But - in her long preservation days before rebuilding, Flying Scotsman did operate on the WCML, and the journey reported was from Carnforth to Carlisle then returning south over the Settle to Carlisle over Ribblehead. So technically, if accidentally, correct. It might have been better for them to just say "main line".
