From what I think I understand I can run several trains at one time without having the block and toggle switch setup. Here is what I would like to know. Lets say I have a train running on my main and one in my yard putting trains together can I set my train that I have running on my main to a set speed and let it go and then switch over to my yard and move things around without have to have a block system? My layout will run 2 to 3 trains max. Thanks
