A lady from an old ad on the train.
I love riding on the train as long as I'm sitting, preferably in rows facing forward, but those wall-clingers can be nice, too.
I like sleeping on the train. I love the trains in the country side, or the Bullet Train to Tokyo from my old, small town.
I've always held that trains are the most romantic mode of transportation, in the aesthetic sense...like who knows who you'll meet. I love that scene in Tenchi in Tokyo where they meet and neither even know who the other is.
