I tried to add any detail I could see to the model.
It started out as a black Athearn shell.
The OMI drive was for the RPP C40-8.
It was an easy fit, and had the correct hanging air tanks as opposed to the bottom mounted on the production model.
Another difference is the dynamic brake inlets and exhaust.
The demonstrators had three of each, production model two.
I'm glad you like. I too love the UP colour scheme.
I have an Option Visor x5. I also use with it a pair of glasses that are a bit stronger than my regular pair.
No, I'll be 74 my next birthday. When I hit 40, my arms became to short!
