Also, most of my trains only have two colors. For this one I used all stains like my others. However, I used three different shades on the train. Then I used a completely different fourth shade for the rocker assembly.
While I'm happy with the previous mentioned changes, I made another not so noticeable change on this one that I'm unhappy with. Since I make very little profit on these, I tried cutting down on some of the labor for this one. In the final assembly process, I normally take extra time to drill and counter sink each hole. Then I glue and screw everything together. After that, I cut short sections of three eighths dowel and plug each and every hole and sand smooth. I still done that for all load bearing and important joints on this one. However, for other joints, for example the slats on the boiler, I used my air powered brad nailer. While everything turned out fine, I just am not happy with it. In the future, I'll go back to my normal method, if only to satisfy myself.
