The RGS fell into the hands of the receiver in 1896 after the bankruptcy proceedings that began in 1893. The receiver was none other than the Denver and Rio Grande. Sooooo, from 1896 to 1929 the RGS was little more than a branch or division of the D&RG, then D&RGW after 1923. Therefore, all of the forms used during that period were courtesy of the D&RG(W) - Train orders, clearance cards, coal tickets, train registers, Dispatcher's train sheets, you name it it was all on D&RG standard forms. When Victor Miller took over as Receiver in 1930 he began replacing many of the forms but a lot of the D&RGW stuff was used for many years later.
So there you have it in a nutshell. Parent road provided the paper.
