Adding Minecarts into game for help transfering Materials

The forums section doesn’t have an ideas Topic or a Support area. Anyway. I have an idea I wanted to see if someone would want to put this idea into the game. The Trains don’t come out until Tier 6 and cost a lot too build. I need something cheap until I can save resources. Has anyone thought of adding minecarts into the game. Should be in Tier 3 and shouldn’t cost that much. On a smaller scale. The engine needs fuel of some kind. and each cart shouldn’t have anymore then 4 slots that can 100 material. Like I said on a much smaller scale. I mean not as big as the train.

Well there are the tractors and trucks

I think he meant something that can go on rails but costs less

Yes, That’s just what I mean. I can keep adding more carts and so on. The minecarts engine can use biomass or biofuel or just fuel. It’s just 1/2 the the size of the train and cheaper to make.
