Not so good for listening to on trains: Love Is All; Delta 5 KRS comp/reissue; These New Puritans; The Queen Is Dead; Standing on a Beach; No Shouts, No Calls. The reigning champion of train-appropriate records is still Either/Or. The key is genre but also mood; anything jerky and aggressively up-tempo (post-punk obviously a no-no) doesn't cohere with the locomotive roll and you end up unable to enjoy either the music or the motion.
Trains really are the transportation of the future. In addition to the constant promise of Lady Vanishes-style Hitchcockian shenanigans you also get, on most trips longer than eight hours, double-decker levels with staircases, crazy-spacious bathrooms, water fountains, exciting theme cars (observation! dining! ladies' lounge!) and an entire bank of seats to yrself, since everybody else has paid triple the price to get an inner earache whilst squished into an airplane seat between a crying baby and an investment banker scream-brokering into his cell phone.
I could live happily on this train for several days, or as long as the carrot stick supply held out. If I stayed on I could be in Portland by Thursday. At the moment I am scooting through the marshes of Wisconsin. Did you know Wisconsin had marshes? Neither did I. It also has some smallish mountains that, on second thought, are probably only ambitious hills. In Michigan there were wild turkeys. See America by train! It'll surprise you!
