If you could have kept that turbine at full speed/full load most of the time, they'd have been winners. But road locomotives only spend about 15-20% of the time in notch 8. -Don (Random stuff, mostly about trains - what else? http://blerfblog.blogspot.com/) Reply Leon Silverman Member sinceJuly 2004 785 posts Posted by Leon Silverman on Tuesday, January 31, 2006 4:58 PM Turbines burn fuel at all speeds The UP 4500 HP Turbine burned fuel at the rate of 600 gallons per hour (gph) at full power but idled with a fuel rate of 300 gph. By Comparison, two 3000 Hp diesel electrics would burn 304 gph at notch 8 . The turbine's advantage is only their high horsepower, not better fuel consumption.

I remember seeing videos of some turbines flaming up in ways they shouldn't have...
