One of the most interesting things I saw on the rails when I was in Japan this year was on the Shinkansen (Bullet train) from Kyoto to Tokyo (and back again).

One of the most interesting things I saw on the rails when I was in Japan this year was on the Shinkansen (Bullet train) from Kyoto to Tokyo (and back again). Every time the train guard went through, when he got to the front of the door he'd turn around, do a 180 spin to face the passengers and give them a salute before 180 spinning back and going to the next carriage in front. I know it's a cultural thing but it's a nice touch.
