But our fat fingers are generally unable to reach between two boxcars on track spaced that closely, so 2" or 2-1/4" is usually a good compromise, with up to 2-1/2" in yards (which we reach into more often). On curves the spacing really depends on the longest equipment you've got. Use two on parallel tracks to check for sideswiping problems, and gauge the center spacing from that (give yourself up to 1/4" of tolerance).

What is the recommended safe centerline spacing between track. I have some 18" radius curves and while I don't operate any long equipment, I don't want to have any problems with overhangs on curves.
Thanks,
