I am currently working on a project to build a custom train with extra features such as cannons and gatling guns added onto the roofs. This video shows the basic pieces to the structure I have laid out, I can combine both trains from single player as well. I plan on releasing this mod once its finished but thats only if the game can go without being broken. So while I am working on this, expert modders can feel free to use their powerful modding skills to fix the game. Thanks for subscribing and stay tuned
