Or you recast the service somewhat, and InterCity runs the true long distance stuff (e.g. a 2tph Liverpool-Manchester-Hudds-Leeds-York-Darlington-Durham-Newcastle, and the Manchester Airport to Scotland which now very much is a true long distance service) with long 80x formations, and "Regional Railways" runs the regional stuff as regional stuff. There's not really much conceptual difference between the former NorthWest Express services to Barrow/Windermere and the Cleethorpes TPE, for one example - the different branding had more to do with BR (like most European railways) applying branding to service concepts, and the use of 156s on those services wouldn't quite fit the TPE/Alphaline service propositions.
