Station A was one of three mines, A, B, and C, in the Coalinga Hills where coal was mined. The coal was transferred from mule-driven ore wagons, then by coal cars pulled by Old Betsy to the transfer dock at Alcalde in Warthan Canyon. From there the coal cars were hooked to a Southern Pacific engine and pulled to Goshen near Visalia, California. From Goshen, the cars were sent to points north and south. On April 3, 1906, the City of Coalinga was incorporated, deriving its name from Coaling Station A.
