Sitting here tonight watching the History Channel's show Modern Marvels: Freight Trains. I've seen it before, but it's always fun to watch again. It tells all about how freight trains evolved and how the new super locos are constructed. It will be on again tonight at 2:00 am (central) and will also apparently repeat later this week. If you haven't seen it, it's worth it. This time around, it's sponsored by CSX! I'm DVRing it for later viewing as well.
