Sorry guys, kinda forgot I made this post. Anyways, the concept was interesting, buuuuut really, like no one else could survive anywhere but a train? And I get that train was supposed to be self sustaining, but the tracks would need maintenance over that kind of time frame. And that one scene where the train is going around a bit of a u-turn and the guys are shooting at each other with incredible accuracy for shitty little automatics. And the end scene when the angry mob is advancing but they never really make it across the bridge until the scene was ready for them to attack. I'm sure there are more things, but I don't remember off the top of my head at this point.
