Why the RI paint scheme? Probably unless you worked in the marketing or purchasing department, nobody knows for sure, but, if you follow the timeline, the maroon bow-wave striped diesels came on the property years before the Pullman-Standard streamlined cars. The first passenger diesels (3800-3804, IIIRC) were in the same bow-wave scheme as the early freight units, except for spreading the bow stripes apart about a foot or two to allow room for the Minuteman logo, and dropping the wings on the sides. This brings you to about 1946-47. I guess that, at this point, the B&M tried the RI scheme in an attempt to coordinate with the stainless steel sided passenger cars. If this were true, however, one does wonder why the RI style back end was white and not silver, but that discussion is second only to the number of angels that can dance on the head of a pin. At any rate, it appears the the RI scheme was, in technical railroad terms, an "oops!" - maybe because they were "all dirt, all the time" - because after 3805-3815, again IIRC, they went back to the bow wave. I believe both schemes were designed by GM. Certainly the bow-wave was, because it also showed up on the D&RGW and Lehigh Valley.
