Attack a product, fine, go for it. Attack users of a product, automatic "troll" whenever I get mod points. Behave.
Ok, so it's not an *existing* product, but I love the fact that following your sig to the letter would have you modded troll.

Surt is right, excavation is always more expensive than elevation.
Not "ALWAYS". Usually yes, but you are ignoring the fact that many cities have already weighed the costs of aerial and subterranean railways, and most opt for subways. That would suggest that for long railways there may be some factor that makes tunneling cheaper than might be expected.
(Before all the arguments about surface construction etc. break out, consider the Chunnel. They had the option of simply sinking a watertight tunnel, or even floating a tunnel with a bridge of some sort to allow water traffic, but they decided to dig. Economics figures into engineering projects as well. If digging is cheapest option, you will start digging.)
