What an amazing TR! Loved the multiple travel modes, and how much you packed into such a short trip. I did wonder how many people stayed outside of Paris and simply caught the TGV in for the day to spectate the various free Olympic events, especially like the road cycling or the marathon.
I, too, prefer the old TGV power car design. The TGV Duplex is one of my favourite trains in the world, despite the French quirks.
Very enthused!
