The Missouri Pacific had the largest group, 146 units, both high and low nose.
The Texas & Pacific had 5 which would go to the Missouri Pacific making that total 151 units.
Here is my rendition of a T&P GP18. Started with a MTH GP20 and tweaked it.
Used Red Caboose GP9 parts trees for most of the changes.
Cut off turbo stack and added the two exhaust stacks. Added a headlight in low nose. Upper headlight has oscillating Mars light. Sanded off the cast in grab irons and added the separate grab irons. Added bell to roof.
What I did not do was change the louvers on the car body as there was a subtle difference between the GP20 and GP18. Also, many of the MP and T&P units had a different style fan cover over the 48 inch cooling fans..
Applied paint, and Micro Scale decals, which included the nose stripes, and I am pleased with my representation of the T&P GP18.
Pictured below is the MTH GP20 turned GP18, and a MTH GP9 in the background in factor paint.
I have since adjusted the headlight as the LED was sticking out to far.
