This short branch was originally built for Goodyear Tire and Rubber Company, which owned cotton fields south of Chandler, AZ. As can be expected, a town sprang up at the end of the branch line, naturally named Goodyear, AZ. The branch line connected with the Southern Pacific at Pozo Junction.

Goodyear Rubber sold their cotton farms in the 1920s and setup a new cotton farming operation in the West Valley; today, this is the present town of Goodyear. The original town of Goodyear, which had a Post Office, was now renamed to Casaba, AZ, which remained at the end of the now Casaba Branch until it was abandoned in 1930s.

The entire branch itself is now abandoned. The filing includes most of the line except for the first 1/2 mile or so near Pozo Junction; the remainder was pulled up in the 1960s. The town of Goodyear/Casaba is considered a ghost town today.
