If you mean "The Hoosier Line" on the light grey...yes it was gray... band across the top of boxcars, that would be 1952.
Ok I'll bite: Was the band with "The Hoosier Line" -ALWAYS- light grey..? ...or did some re-paints get done in white?
...and just how light was the 'light' grey? i.e. one drop of grey in a bottle of white??? In several color photos from the late 1950s... both the band and the lettering seem to have weathered-out to nearly the same shade.
