Bridge Building Game - educational and addicting as hell

[asshanson]

Um, no idea on map pack 2 level 7, there is no yellow line that says what plane the train travels on, the train wont ride on a single track I make for it, starting with either the high or low endpoints.

EDIT: nevermind, I had to turn on the button for build deck, it's a level that doesn't specify where the deck has to originate.
