These are, I promise you, teaser trailers for the new Superman movie, Man of Steel. One narrated by Kevin Costner, the other by Russell Crowe. They get to the Superman part eventually.
There's no speeding trains or bullets, but then, by all accounts this is supposed to be a much more serious Superman movie than those we're used to. Hence the lack of speeding trains, bullets, and the strange presence of "that sad music from Lord of the Rings".
