What was ATSF abandoned Prescott in 1984 and the tracks were pulled up right after that. There were floods during Sept 1983, which caused washouts of what essentially was a 26 mile spur into Prescott from a station area called Drake, which is on the Peavine.
The Peavine basically goes from Williams Jct all the way through Wickenburg to the Phoenix Area. The Peavine ends at approximately 75th Avenue and Olive Avenue in the Peoria Area. From that point, yard limits go approx. 15 miles south to Mobest Yard at 19th Avenue/McDowell Rd in Phoenix.
One other interesting note about the Peavine is just west of Wickenburg, the Arizona California Railroad connects with the Peavine and has trackage rights on the BNSF to Phoenix. Usually cars are swapped at a long siding in the Morristown/ Castle Hot Springs area. I have seen the the trains in that area really early in the morning (usually 3-4 AM)
I originally am from NY and came to AZ about 20 years ago. I am very interested in the railroad action out here. There is an excellent book called "Santa Fe to Phoenix" (Railroads of Arizona-Volume 5) by David Myrick. That book, which I have, gives the entire history of the Peavine and its predecessor railroads.
