Train

[fathom halo]

Hello, help me, I would like to know if in some way I can make two entities tied to each other, that is, one tied to the other and not to the player of course, I want to do something like a train, I also want to know if I can put a way in that can only be moved in a block like the tracks

I don't think you can, you can make them ride each other but the ride position behind their backs as to make it realistic without leash
