Whether it's a locomotive, rolling stock, or vehicle, show us your custom paint job(s). People like AMCDave and brotherlove do fantastic paint jobs, but it doesn't have to be perfect to share. The big manufacturers have a lot of variety but that can't satiate everyone, especially those of us in love with more obscure railroads or rolling stock.
I'll get it started with my first custom paint job from a few years ago. This is a Lionel New Jersey Transit GP-40 repainted to resemble a White Pass and Yukon Route DL-535. This took a while to do, but you've got to start somewhere.
