Steam Question on the Shenandoah Division

These weights may vary a little depending on source (and my arithmetic may vary most any time).

K2 had 248,150 lbs on drivers, 62,038 lbs/axle average
J had 288,000 lbs on drivers, 72,000/axle average

K2 had a much lower driver axle loading than the Js.

A had 432,350 lbs on drivers, 72,058 lbs/axle average

A had a driver axle loading similar to the Js and higher than either the standard Y6 or the improved Y6.

Y6 (as built) had 522,850 lbs on drivers, 65,356 lbs/axle average
Y6 (improved) had 548,500 lbs on drivers, 68,563 lbs/axle average

The average for the improved Y6 does not tell the entire story.  If the entire increased weight on drivers (548,500-522,850=25,650 lbs) is on the front engine (it may or may not be depending on the equalization), then the distribution changes:

Front engine: 261,425 lbs + 25,650 lbs ballast = 287,075 lbs, or 71,769 lbs/axle

Rear engine: still at 261,425 lbs = 65,356 lbs/axle.

Revised weight on drivers: 287,075 + 261,425 = 548,500 lbs
