Big Blow 30by ~classictrains

Photography / Transportation

The Union Pacific's quest for high horsepower led it in all kinds of directions... this included several variations of gas turbines from GE. Coming down off Sherman Hill this train enters the Cheyenne, Wyoming yard limits in the summer of 1968. The trailing unit is another curiosity... a GP30 B-unit.

Heard some rumours of them upping the HP to 10,000, anything to support this? Impressive beast by any standards

~classictrains Jul 3, 2010

According to Wiki [link] they didn't but the rumor is based on an interesting detail: "This may stem from the fact at 1,500 ft (460 m) elevation, that the turbine was capable of producing 10,700 hp (8.0 MW), however the electrical equipment was not rated to handle it."

Interesting, I had heard both the rumour about altitude and the supposition that they were upped, imagine it's the effect of altitude, thanks for that!

Those Gas Turbines must have truly been awesome! My formative train watching in Chicago during the heyday of the SD-40-2 probably was just not the same. At least there were some cool old diesels around in the 80s.

...and there still are today. Remember this stuff was commonplace... or easy to find... in the 1980's. Shoot what you can today. It won't be around forever.

Very true. I may not take as many pictures as I used to but I still have the desire!

Holy crap, cabless GP30??

(the turbine ain't too shabby, either

)

~classictrains Apr 21, 2009

Yep.... UP did this a LOT! There are several hidden in my Gallery because I mostly only list lead units in a consist.

That has got to be one of the most unusual (NOT read: ugly) locos there is.
