Southern Pacific A-B-A-B-A Power Consist
The EUALM was a daily manifest between Eugene, OR and UP’s Albina Yard in Portland, OR. The June 2, 1992 edition of the train ran with an unusual power combination: an A-B-A-B-A set.
The second and fourth units are Tractive Effort Booster Units. Known as TEBU’s for short, the SP received 14 of these road slugs in 1980. They were re-built from retired U25B’s.
Technically not B-units because they lack a diesel motor, they were used primarily in Arizona and Texas. A recent post showed a TEBU on an aggregate train in Houston.
