In the background you can see Northern Pacific Bridge 59 crossing over the Great Northern tracks. The GN depot and train order signal is peeking from the left of the building in the top center.
There is no sign of the roundhouse having been built, but you can still walk around in the turntable pit and there is still a piece of concrete in the middle with a 1903 cast date in it.
