Been a few years,did ride the line with the wife,both the "shoot out" at the station(Williams)and the onboard "robbery" are somewhat "historical"
reenactments based on AZ state history,can be entertaining with the kids.
Rode behind the 4960 mu'ed to FA/FB/FB set in 1 of the SP coaches,decent track, 40-45 mph speed. there are AC coaches and Dome cars,extra fare however.
The train wyes and backs into Grand Canyon Station,owned by the Park service. There's a shuttle bus service to various points in the Park.
Heavy car traffic during the summer in the Park,beware!
Have enough time to visit 1-2 park attractions,and view the Canyon before the return trip.
During the "peak season" GCRY runs 2-3 round trips.
One of the other sets in use is the "Boise Budds"(MBTA/Caltrain) set with dome cars behind a pair of F-40ph's.
Can be hauling a Water Tank Car to the Grand Canyon at times as well.
This was before the Xterra buyout of the original owners behind the branch rebuilding .
The Land of Enchantment is not Flyover country!
