Questions About Older Atlas O Scale 2 Rail WDT Three Axle Industrial Switcher

Hello everyone,

I am someone interested in model railroading. I am in my twenties. I am set in HO scale, but am interested in exploring other scale, including O scale North American 1:48 and British 1:43th (the latter I like because realistic chain couplings).

I am interested in exploring trains in other scale, such as American 1:48th O scale.

One example I had the idea for a starter locomotive, is this older Atlas 2 rail O scale WDT industrial switcher in Union Pacific livery with silver trucks. I had the idea of super detailing it, and adding DCC & sound, along with repainting it in my own custom livery.

One facebook O scale 2 rail page, I got some good info on others experiances. Some had removed part of the inner weight to add a decoder, even inside the roof part. I understand that if you want to enter the world of O scale 2 rail, alot of things from rolling stock need to be adjusted, added detail needed etc, you undnerstand what I mean.

What has your experiance been with this locomotive? What should I know about it?
