How bout' a guide on just Arizona

We have lots of railroads to come and watch while your in the state for Arizona Diamonbacks games. We have the Verdy Canyon Railroad, the Peavine. BNSF along old 66, Grand Canyon Railroad. Black Mesa and Lake Powell, and my favorite place…Cienega Creek, its where the Sunset splits into two lines goes over/under itself in a canyon and at the end becomes one line again. One of the reasons it’s my favortie is because my high school sits right next to track #2 and is the bridges are only 5 miles down the road

how about not

What track does the eastbound Sunset Ltd. normally use? The one that goes through the horseshoe curves near Pantano?

How easy/difficult is it to railfan in that location?
Thanks, Doug
