Modular pop-up train concept: Locomotive update (V2)

Modular pop-up train concept update: I've been working on the locomotive and have a rough version 2 ready. Now I need to work on an improved version of the DIE lines, add extra details and fill some gaps. I also want to add three other types of wagons (a flat car, a tank car, and an open wagon) and fine-tune everything one more time. Starts to look like something and I think I'm halfway now. hope to find time during my Christmas vacation to work on this. #paperengineering #popupcard #trains #creativity
