I received this game in the mail just last week, and finally got to try it yesterday. I really enjoyed it! The production values are excellent and the gameplay is simple enough to teach quickly, but deep enough to make really interesting choices and strategies. I am a big fan of Carcassone and Tsuro and I could see their influences (they are explicitly listed as inspirations for Light Rail). If you like those games, or well designed products in general, I would highly recommend this one!
