By 1975, Rock Island adopted THE ROCK image. RI never settled on a single lettering scheme in the maroon caboose era and this continued in the blue era as we see with these two runs. RI 19138 is the earlier of the two since it continues to use RI reporting marks. Even the R logo is taller than later versions. Caboose #19125 now uses ROCK reporting marks and the later R logo. There is also more blue and less black paint.
