The improved ride is the secondary benefit. The reinforced concrete improved
buff loading, the old squeeze issue. Q bi-levels are built to an end loading
strength of 180,000 lb. as opposed to cars like CNW of a 140.000 lb. design.
That is why the former Q 700s are not inter-mingled with other bi-levels.
Metra runs other equipment on BNSF, but not mixed with former Q cars.
