Minecarts - Perhaps it's Time For an Upgrade

Hello and welcome to my first post!

I've been romping around worlds in this game for quite some time and the one thing that's been basically the same in the 11 years I've been playing is the humble minecart. Yes, we can shoot minecarts down rail lines with powered rails and watch the furnace cart struggle to push a train of carts uphill. But what if it would be possible to have a connected train of minecarts, possibly pulled by a stronger furnace cart or maybe even a new type of cart that the player can have direct control of, to carry resources and mobs over miles of blocks? I would like to see trains be possible in Minecraft.

Chains are already in the game, and that could be a way to hook up the carts. Llama caravans already play follow the leader so maybe minecarts can do the same. A controller cart of some kind would only need to go forward a backward along the rails and pull or push the other carts along with it.

I hope I'm not the only one that wants to see a bit more vehicle functionality in the game, and I want to tank you for taking the time to ready this post.

Farewell!
