Oh about the concrete shaking on V2, I feel it too and I don't really see how you can miss it. If you hold on to the rails, you feel them shake, but let go when the train goes by.. and you still feel the vibration. Which would tell you that the conrete is shaking because that is the object you are standing on and if you're not touching anything, that has to be what is vibrating. It isn't really a shake though, it IS more of a vibration. Not bad, but I definitely feel it when I go on v2.
