Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 45, p.195. Works numbers were 33508 in June 1909 and 40803 in November 1913.
This medium-sized Prairie was essentially a duplicate of several dozen other low-drivered short-line engines sold by Baldwin to railroads and industries across the United States during this period. It arrived on the PP rails in Florida to transport the dug-out phosphate deposits to the Charlotte Harbor & Northern at Cottman or Ridgewood. The CH&N soon bought both branches.
Like many of the northern Florida phosphate companies, Palmetto Phospate was bought by the American Agricultural Chemical Company, then the second largest such company in the United States.
