There's not much difference really. If you're lucky you might get into a
former first class Sunshine Express car (the larger cars). Or you might
want to ride in an ex-Pullman "DAV" car/van. Or, if you're a real
enthusiast you might want to ride in the Davidson "BV" car/van built in
1886.

No, down trains go up the hill. :)
