Minecarts connected with chains

It would be a great addition if minecarts could be linked together using chains. By using a chain on two minecarts, players could connect them and create trains that move together along rails. This would allow players to transport multiple chests, mobs, or players at the same time, making rail systems much more useful and interesting. For example, players could create cargo trains from mines to their base, automated item transport systems from farms, or even rail networks between villages. Using chains would fit perfectly with Minecraft’s mechanics since they are already used to connect things and represent physical links. This feature would also make minecarts feel more complete and encourage players to build larger railway systems.
