What is it about trains and working?

There's something special about simply being on trains. When I have my notebook or laptop, the items that have sat on the long finger, or the work that is a little stuck, seem to unravel…. and flow with the movement of the land passing by. Is it the defined time? Is it the actual motion of the train? Is it the sense of being in an inbetween place: nowhere to go: nothing else to do? the internet connection is too slow to get too distracted…. Being on a train is like having a deadline without the adrenalin. The physical rhythm seems to allow the necessary changes of mind and perceptions to let go: to move forward. Or maybe it's all in my imagination….  maybe it's just me?
