SP Slug Set
After testing the concept by borrowing a pair of Seaboard Coast Line U36B's and a MATE, the Southern Pacific Railroad put the concept into play by puting a pair of bought new EMD GP40-2's paired with TEBU's (Tractive Effort Booster Units). The SP built the prototype TEBU from a GE U25B, then sent other U25B's to Morrison Knudson to be converted into additional TEBU's. The set seen here 7949/TEBU 1603/7948 spent several years hauling Copper Ore on Southern Pacific's Hayden Branch in southeastern Arizona.
