Chatzi473,
I don't want to sound like I'm criticizing your video, which I'm not, but if you intend to continue doing video (as opposed to still) photography I would recommend you invest in a decent tripod. A fluid head would be nice, but it can wait until later (IIRC you are a starving student, yes?) And I would try to concentrate my photography so you are on the lit side of the train (yeah...I know it's difficult...especially in the canyon) but a couple great shots are better than a whole bunch of dark ones. I should know, I've got a closet full of 'em.
Other than that, it is pretty good.
