Forgotten engineering, steampunk pneumatic tubes, political machinations: I love stories of grand efforts that get overlooked by history, and trains, so this would be a winner. But then, the art: the puppets, the sets, the costumes! And excellent back matter! Sadly my local library, like many, wraps the dust jacket in a milar/paper cover which is then taped down, so I couldn't enjoy the bonus material on the art, but I get it's really cool. I'm only sorry it isn't also a short film, because that would be awesome!
