Add more Transporting Wagons. I always use trasporing between cities, from one city to another city. But I still not have enough transporting wagons. 6 transporting wagons is not enough, increase them to 20 Transporting Wagons and LT incearse to 20k LT. It will be better when u transporting a lot of materials like me. Its not will be limited to maids like Magnus content.
