Southern Pacific 7399

Southern Pacific 7399 was constructed in September of 1966 as Southern Pacific SD45 #8837 and it was delivered to the Southern Pacific Transportation Company that same year in 1966.[1][2] Then, in October of 1981, #8837 was rebuilt by the Southern Pacific themselves under the Southern Pacific's M-99 rebuild program into an SD44R and renumbered to it to #7399, thus making #7399 the only example of the SD44R.[3]

No. 7399 was later repainted into the Southern Pacific's Daylight paint scheme along with SD40R #7342 and remained in that paint scheme until being repainted into the Southern Pacific's "Kodachrome" livery of the proposed merger between Southern Pacific and Santa Fe, but then, in November of 1981, 7399 was repainted into a second variant of the Daylight paint scheme. Until emerging with a new SP Scarlet and Daylight Orange long hood, along with a black roof, trucks, fuel tank, pilots and plows.[4]

It lasted into the days of Union Pacific when Southern Pacific and its parent company Rio Grande Industries had merged into Union Pacific.

No. 7399 was later retired from Union Pacific's roster and sold to EMDX on October 31st, 1998, and renumbered by EMDX as 2816, leased back to Union Pacific as UP SD40-2 #4766 on September 4th, 1999, and returned to EMDX.

As of 2013, Southern Pacific 7399 is currently operational with EMDX as EMDX #2816.
