Have you ever taken an international trip from your local station?

Does Heathrow Express from Paddington to Heathrow count? 

[Bob_Blakey]

I almost always book such trips well in advance, to take advantage of cheaper tickets in GB^▸ (Great Britain) / on Eurostar, and then use either the Rail Europe or individual country rail service websites for onward travel, generally from Paris. I haven't yet had occasion to checkout what difference, if any, the merger of Eurostar & Thalys has made to mainland Europe ticketing options.

One rather jolly exception to this, some years ago, was DIG>PLY^» (Plymouth - next trains) with GWR^▸ (Great Western Railway), a pleasant early evening stroll to Millbay Docks, Brittany Ferries to Roscoff, and then SNCF^▸ (Societe Nationale des Chemins de fer Francais - French National Railways) to Brest, changing at Morlaix, to join a friend's yacht for a lovely sailing trip as far as Morbihan and then back to Dartmouth. I am pretty certain that absolutely no through ticketing options existed at the time.
