I have always naturally assumed it would be the 4-8-4 Wyomings..
but im comparing stats of the LV 2-10-2's compared to the 4-8-4's.
2-10-2 data:
Engine Weight 370,000 lbs
Tractive Effort 72,620 lbs
Factor of Adhesion (Weight on Drivers/Tractive Effort) 3.98
http://www.steamlocomotive.com/santafe/?page=lv" onclick="window.open(this.href);return false;
T2 class 4-8-4 data:
Engine Weight 451,000 lbs
Tractive Effort 66,982 lbs
Factor of Adhesion (Weight on Drivers/Tractive Effort) 4.10
http://www.steamlocomotive.com/northern/?page=lv" onclick="window.open(this.href);return false;
The 4-8-4's also have "power computation" data at the bottom of that page.
The 4-8-4 is heavier, but the 2-10-2 has a higher tractive effort.
Im sure there is more to "most powerful" than just the tractive effort alone,
but based on that one number alone, it seems the 2-10-2 is "more powerful" than the 4-8-4,
although I doubt this is actually the case..
It seems unlikely that a 1917 locomotive would more powerful than a 1932 4-8-4,
so im assuming the 4-8-4 is actually "more powerful" in reality..but I dont fully understand what the numbers mean..
can anyone clarify?
thanks,
Scot
