Ideea is very simple if armored trains and/or the flametrower wagon are installed.
However, insted of thoes 2, this 2 turrents, but on train wagon. Also the artelery wagon is perfect for "adding and using ammo". And for no complication (like how the armored train works) i suggest to just create separate wagons, like 1 with one turrent, another wagon (mk2?) with 2 of them. And for the cannon, well either an animation where they can roate left to right (since with a train you don't need front or back) and like this they are facing exactly where the enemies will come from. If however making them roatate is to complicated them just both (i asumme one in front of the same wagon and one in the back of the same wagon like how armored train's turret's work, but without the gride and equipments) are facing just 1 single direction. Why? because if you want the other direction all you need to do is rotate the wagon before placing it.
