Among the items recently scanned/posted online by the Canadian Pacific Historical Association is a document that may be of some interest to D&H fans - an official painting/lettering diagram for what was planned to be an order of 50 SD60M locomotives numbered 7901-7950 that would have been painted in full D&H lightning stripes.
It'll be interesting to see if any model railroad companies produce a "might have been" rendition of this.
It might be possible to replicate the lettering and stripe using available decals as well.
