my ESPEE MODELERS ARCHIVE
California's Railroad to the U.S. 1861 - 1996
SP proper received its first 'covered wagons' in May of 1947, (SSW got FT's earlier). Placed in Classes DEF-1 and DEF-2, (later DF-1 and DF-2) deliveries continued until February of 1949 when superseded by EMD's F7 model.
All were delivered in 4 unit ABBA sets painted in Black Widow paint.
Southern Pacific originally numbered F units in sets of four, with one number and an alpha suffix. F A or cab units were suffixed A and D, F B units or boosters were suffixed B and C.
Due to locomotive shortages on the Atlantic Lines (Texas and New Orleans) starting in 1949, all F3 units were sent to the Texas and New Orleans, except #6138, 6139 and #8038, 8039
In December of 1949 SP decided the alpha suffixes had to go, and so a general renumbering of all system F units took place. The F A or cab units were given 61** numbers and the F B units or boosters were placed in the 8*** series.
Some of these F3's came back to SP and returned to original numbers, and some were rebuilt as F9m's.
