The RailRoader was born out of a lack of truly portable motorized rail systems for moving time lapse shots. I needed something that would be fairly lightweight and fit into a bag. My ‘field test’ was a pretty demanding one: carrying this thing literally around the world. I am going through and editing the footage I took using this device now and will post it here shortly.
