With axleboxes centered in their slots my TICH has about .025" total free lateral movement in each axle. Primarily this is to allow the axleboxes some lateral relief as they ride in their horns. I didn't have anything to detemine this by . . . it just seemed about right to me. Eventually the loco will let me know if I gave it enough. Regards, Harry MODEL ENGINEERING DISCUSSION LIST.
