Woot indeed. We had this(the older version, of course) on my Mindcrack server that I used to play, but we never freaking used it since I couldn't power the damn thing via EU. Also it was a bit buggy, and we were planning to move to Ultimate soon, anyways.
It looks like a very cool mod, and I'd like to see more long-distance transportation not involving portals or retardedly-expensive teleporters.
I love trains, and the idea that I get to build them is great. But do I get to use them? Because Minecraft seems like a really poor environment for the sort of thing that is made to move things from one place to another in a really expensive and labor-intensive way. No one used a train for small amounts of cargo (except the government), and since you can condense a mountain down enough to carry it... why a train?
I mean, I build train setups myself, but I do it because I like trains. It's literally the least efficient possible method of accomplishing my goals and that makes me sad.
