NS 8025 as the Rear DPU on M-PRNP-02 at Ames. The lead unit was UP 8174 which was formerly the Nebraska Big Red Sticker unit and the mid DPU was CN 3202 which is the 1000th Tier 4 GEVO constructed. I’m unsure why CN 3202 isn’t on heritage units despite its recognition probably since it’s painted as a regular CN unit
