Filmed on a Panasonic Lumix GH3.  Color settings set to -5,-5,-5,0 for maximum post flexibility.  There is some camera wiggle at the beginning as I had to spin the tripod around to get the train (I was filming something else to begin with).  Hopefully I got enough of the train for someone to find this useful.
