Tractive effort
My calculation: 18x18x24x200x0.85/48.5 = 27,256 lbf. Biscuittin (talk) 23:07, 21 November 2015 (UTC)
 * The quoted figure of 29,527 lbf would be correct if the piston stroke was 26 inches. Biscuittin (talk) 23:10, 21 November 2015 (UTC)
 * This ref confirms piston stroke is 26 inches. I will correct the infobox. Biscuittin (talk) 23:20, 21 November 2015 (UTC)
