You will need the F3 from DTM to use this re-paint.  https://store.steampowered.com/app/1869390/Train_Simulator_Union_Pacific_F3_Loco_AddOn/
The Zephyr was one of the most famous trains in the golden age of rail travel and the Chicago Burlington & Quincy also known as the Burlington Route was early into diesels to haul their part of this Chicago to the West Coast as well as many other destinations.  The F3 was called upon for this task prior to the E7 and E8 later on.

When the E's moved into hauling the Zephyrs the F3s were regeared re-painted and sent into freight service where they served until retirement.


To install this run the installer and then copy F3_CGW_01.GeoPcDx and the F3B_CGW_01.GeoPcDx from the DTM\F3 UP\RailVehicles\Diesel\F3_Engine_CGW and paste it into your new F3_Engine_CBQ-frt folder.
That should do it.  Enjoy this iconic locomotive.
