@chasing_steam: Sierra No. 3 stretches its legs out near Rock Pile, working hard with smoke rolling skyward as it hauls two of its oldest passenger cars from the 1800s. With its classic diamond stack leading the way, it’s a rare glimpse of the railroad much like it once looked generations ago. #sierrano3 #steamtrain #railfan #historicrailroad #trainvideo Thanks to @Dynamo Productions for putting this event on!
