This morning I headed out to try to get some fall photos with 35Q headed east. After 35Q crept up to a stop signal between Front Royal and Linden on the siding, I figured a train was headed west on the single track. I waited at Markham for just a few minutes before NS 290 rolled by. Photos and Video below.
