hi,
My model pix have become corrupted so no model to show (I have a pair of Atles -2, not accurate but close enough for the 'end-of-era' modelling I may do one day), but here's the data for the 1983 purchase of D&RGW desperate for additional engine power east of the Rockies with run-through alignments increasing traffic range and density.
"Purchased second-hand from Conrail. Had temporary unit numbers until repainted in 1984-1985, in a darker orange color than rest of fleet. No low-nose headlights on these units." -Jim Griffen.
