I started off with a undecorated Athearn blue box, Making the change to GMD a few detail changes had to be made to the unit such as the bell, the rear tail light and the front head light, sunshades, and the brass snow shield was added, the patch up of the original emd hand brake and also I do have the rock lights for the unit. Also did a bit of weathering to it. It still under some work right now been busy with work I haven't had any time to work on it and look for the other detail parts which are need to complete the unit. I started this unit 2 years ago and did some work slowly after. I will find and post the photo's of when i started to work on the unit. Hopefully I can soon get this unit finished.
