I’ve been always asking myself this question on why we can’t make little minecart train with chain item. Even MC story mode and MC dungeons had them but the base game doesn’t? We need a new update to make these more useful… to give a full reason to use the carts a Carts & Rails update is what we need.
I’m less bothered by the fuel cost as the total lack of control over them. They seriously need a rework.
