B30-7 863
B30-7 863 at Salt Lake City, Utah in April 1978.
Two additional locomotives are partially visible in this view.
The second Frisco unit is U30B 848. In this view the Frisco units show major spotting characteristic differences between the General Electric U30B and B30-7. On the later model these include the larger flared radiator section over the rear walkway and the wider stepped mid hood section, seen between the “R” and “I” in FRISCO.
Also interesting is the different make and model Union Pacific unit. The Frisco locomotives are in a multiple unit consist with a unit built by General Motors Electro-Motive Division. The right locomotive is either UP 84, a DD35A cab unit, or UP 84B, a DD35 cabless booster unit. The DD35 series featured twin engines and generators on a single underframe. The DD designation denotes two 4-axle trucks – 8 powered axles in total. These single frame, duel engine locomotives each produced 5,000 horsepower.
