I noticed that he said he paid $280 one way and I thought that was extremely cheap. I’ve paid more than that NY to DC one way.
I didn’t know the Shinkansen was so (relatively) inexpensive,
TGV for a similar distance (Paris to Annecy) is about €180 one way in first class and ICE (Berlin to Munich) is €180-280.
Of course TGV and ICE take 4 hours to cover the 400 mile or so distance whereas Acela takes just under 7 hours
