@Carl J posted:modern wireless Command Control like Lionel introduced makes it very easy to get 2 trains ( and more!) on the same track working at different speeds without interfering with other locos/ speed direction or need of all the wiring blocks and relays.
What is being done here with relays and whatnot is so much more than what Command Control can offer alone.
Command Control does not have this automatic signal control nor automatically keeps trains from colliding. Once this setup is up and running, no user input is required.
