Train geeks! :)
I've travelled Europe by train as well. Yes, TVG in France is pretty cool. I loved the old stations, modernized, but still showing their history. We travelled in a sleeper from Salzburg to Paris overnight one time. So cool! I felt like James Bond or something. Pretty cool.
I have't been to Japan but am sure the trains there are cool. I guess all trains are ok, commuter trains just seem to bring thoughts of going to work and that sucks! :)
