Mixed up numbers?
Posted by eagle1030 on Monday, August 26, 2013 4:29 PM

Regarding Ed Dickens interview with trains, at the end of the article he claims that after 4014 is restored and converted to oil, it would produce 7200 hp.  Everything I have ever read has put a Big Boy's drawbar hp around 6000-6200.  So:

1.  Is the 7200 horsepower in the pistons?

2.  If it is indeed drawbar, does oil-firing really increase horsepower that much?  Even as a UP fanboy, I find that really hard to believe.

Hello,

UP fed the Big Boys poor low BTU-per-ton coal, whereas oil is relatively high BTU-per-ton. So that may be a part.
