Regular price $149.98 Sale price $127.48


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.

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.
