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.
They need to make the carts react the same as if you were riding in one. It’s dumb to have to increase your powered rails for chests or animals.
