Intentional Camera Movement From A Train In Skagway AK

I took a ride on a White Pass & Yukon Railroad train while in Skagway last week. The views were stunning, and I spent a lot of time on the end of the rail car outside taking photos. Along the way I played with a hand-held long exposure app on the iPhone called ReeHeld (by REEFLEX). These are the results. For just playing around I think they turned out OK (especially since the camera was being knocked around by the rough tracks). The first one seems the best one to me though.
