Down at Rocky, a westbound trackage rights BNSF train waits for Amtrak #5 and the Ski Train to clear before continuing uphill on the Moffat Route. This was taken as Amtrak #5 was clearing a loaded UP coal train on Clay Siding, uphill from the curves. To see Scott McClarrinon's take on a similar scene (and to gain perspective on this shot), see his photo here: Amtrak at Clay, coal at Rocky Siding>.
