my ESPEE MODELERS ARCHIVE

California's Railroad to the U.S. 1861 - 1996

16 units built

The 16 AC-5 class engines were built in 1929 by Baldwin. These were the same as the previous AC-4's with boiler pressure of 235lbs, a weight of 622,000lbs and a tractive effort of 116,900lbs.

According to a note on the SP lettering drawing dated 12/30/49 all AC class engines assigned to Sacramento, Shasta, Portland, and San Joaquin Divisions shall omit the large SOUTHERN PACIFIC on the tender sides, also F class engines on Shasta Division. Photo evidence shows that this was often but not always the case. Charles Givens

All scrapped by 1955.
