My 2 cents: i think the picture in the bottom set is a variation of a truck stop. Its not an elevated track, theres a rounded part on the left most side that meets another red piece, this intersection is at too weird of an angle to allow a train to navigate from one section to the other. Also, if you look at the box art for the passenger train, it doesn't look elevated. Further, if that is in fact elevated track, why would they have a train station for passengers with regular track when the only train with regular track would be the cargo train? Makes little sense. Going back to the truck stop idea, the red in the banner looks like it could be the top of where gas pumps are. just my guess. Whether or not I'm right, I'm ridiculously excited about that new cargo train!
Edit: Also with all the new trucks being released (Octan Tanker, the red one in the cargo train set, the yellow one behind the ladies head) it only seems proper to have a truck stop for them all
