Whether or not you realize it just waiting on the platform behind me, that train just two tracks away from where you are sitting is barreling past at an unbelievable speed.
My initial estimate would be a slick two hundred kilometers per hour or so. The gush of wind first pushing me back and then sucking me back again attests to that fact.
All those kind folks enclosed within that speeding piece of metal have no idea of how fast they are speeding by, nor does a single passenger realize that on the platform there is this gray-haired observer trying to philosophize and think things up.
Everyone goes on with their own lives as if it all doesn't really matter, which is alright.
