transportation improvements

Hello Minecraft community, I hope all is well, I have a suggestion for the game. What idea is it? What does it treat? Well, it's about making improvements to the wagons in the game and transportation in general, (1) the wagons could be connected with chains or ropes along with slime PS: you can optionally place lamps or torches (2) you could as a test official driver add horse carriages in MC java and BE with chests and can ride people (3) using a command block /railway_set_minecart_auto~~~ will be able to create automated trains with wagons, will stop player assigned stations, and will only run on normal rails, you can't with propelling rails. Those were my ideas for Minecraft. Thanks for reading this message. See you later!
