Although I been working with trainz for many years I never used portals until now. I use specialized loads in my routes which I program each railcar to carry. I was wondering if I could somehow program the portal to generate cars that are programed to carry specialized goods such as wire coils or 12m steel rods? It would also be nice to have trains loaded with coal or iron ore generated from the portals. Does anyone know how to do that? Thanks in advance.:wave:
