According to Espee’s internal memos, the Bicentennial locomotives were affectionately referred to as “Snowflakes.” These unique and colorful Espee locos appeared quite often separately on company public relation exercises, with #9389 being a part of most helper consists for the Freedom Train, and GP40P-2 #3197 was seen everyday as part of the Peninsular commute fleet. The SP ‘snowflake’ paint schemes were all designed by the late Mr. Chester Mack, famed RR designer.

The first unit painted was Cotton Belt (SSW) #9389. This was chosen as being the 600th SD45 to be built for SP, ie. 590 SD45 including SD45T-2’s and 10 SDP45’s. Evidently it was given basic Bicentennial paint by EMD, then completed by SP when delivered to Taylor Shops in Los Angeles in May of 1975. About the same time, that a Southern Pacific loco should also wear Bicentennial paint, so as the GP40P-2’s were about to be shopped, having done a 6 month break-in service on freight, #3197 was selected to be painted Bicentennial. June 1975 saw #3197 (Bicentennial GP40P-2 offered in Genesis ATHG40858, and ATHG40758) roll out in the patriotic paint. To go along with the theme, SP repainted Caboose 1776 in Bicentennial paint. This was originally a C-40-7 built by International Car Co. in 1967 with roofwalks and end ladders. As painted in Bicentennial scheme in 1975. Look for the C-40-7 Bay Window Caboose next month!

  • The SD45T-2 is a 6-axle diesel-electric locomotive built by EMD for the Southern Pacific Railroad. Like the similar SD40T-2 it is nicknamed a “tunnel motor”. 247 were built from February 1972 to June 1975, including 84 for SP’s subsidiary Cotton Belt. From April 1986 to December 1989 about half were rebuilt and designated as SD45T-2R and 24 of the 126 rebuilds were built for Cotton Belt.
  • The SD45T-2 is an SD45-2 with cooling system modifications. The intake for radiator cooling air was moved to the walkway level and the cooling fans themselves were under the radiator cores, instead of above. Tunnel motors were built to perform best in tunnels in mountainous areas in the western United States. The air intake grills at the lower rear of the locomotives’ long hoods were intended to bring cool and clean air into the radiator section. The larger area of the intakes would also provide a less restrictive airflow.
