#TBT Each issue, the editors of amtrakthenational publish their favorite photo taken on and along Amtrak’s routes around the country. For the Aug/Sep issue, they chose this image by joelmattson, who captured the light trails of the Empire Builder as it passed his truck outside Quincy, Washington. “I got there just ahead of the train and set up my tripod at the crossing,” he says. “As I watched it go by, I was amazed by how many colors there were.” #AmtrakTheNational #EmpireBuilder
