Tiny trains for your tiny needs. Makes rails and wagons 1 wide, and shortens the wagons to 3 height. Now you can fit a train in between your assemblers and beacons. Rails still move on a 2x2 grid.
Thank you for making this. I've wanted an intermediary between belts and a full-size trains for such a long time. Tried scaling trains down myself once but I couldn't figure it out.
