An outbound MARC pulls in on track 1 as a CSX manifest waits on track 3, needing fuel from the rack, for the MARC to unload passengers (at the station behind the photographer's left) and push back into the yard, crossing over to the track just to the left of the tower, where it will go replenish its own tank before going to relax overnight.
For my other shots of WB tower, including a favorite ultra wide angle with yellow freight cars, go here.
