Something special for 60 subscribers! A hulking monstrosity of Union Pacific Power, the DDA35
The DDA35 is a cab unit version of the DD35, built exclusively for the Union Pacific railroad. Only fifteen of these beasts were built between May and July of 1965, numbered 70 (pictured) through 84. Powered by twin 567D prime movers, these locomotives were good for 5000 horsepower each. Unfortunately, these locomotives suffered reliability issues (seems to be a common theme), and by the time those issues were ironed out, the writing was on the wall. Their inflexibility and economic downturns of the 70's-80's lead to all units being retired and eventually scrapped.
