I am just getting into Superstreets and purchased some vehicles. I will have one loop of roadway (a dog bone design). How will running multiple vehicles work? I have a hard time believing they will all run at the same speed. Won't they eventually rear-end slower vehicles? I have MTH traffic lights. I am thinking of wiring a relay coil to the red light which will cut power to an insulated roadway section. This roadway section will cut power to the section behind only when it is occupied and so on to prevent cars from rear ending each other. Then when they re-start (green signal), the first section will have one diode to reduce voltage one step, the section behind will have two diodes to reduce voltage two steps and so on. So the first car will take off quicker, the second car will be slightly slower to take off until the next traffic light. I think it might be more realistic too since cars won't take off at full speed. What do you think? Is there a better way? Or will a simple loop run 8 vehicles all at exactly the same speed?

Thanks!

The various vehicles don't run at the same speed.  I've never run eight vehciles on a loop.  My longest 'Streets loop, my "country road" is about 90 feet around.  I routinely run up to four vehicles at once: by picking vehicles that run pretty much the same speed and spacing them out about 20 feet apart I generally get a situation where only every five minutes or so I have to reach out, pick up one car as it comes by, and let another pass (sort of fun actually).  

 

Potentially, you could set up isolation blocks with relays controlled by an isolated outer-rail detection block to cut power to a section (as done with track and trains) and keep multiple vehicles spaced out, but there are problems: the little vehicles are light and don't have a lot of wheels and so they don't always trigger detection blocks/relays well.  Micro-mart sells an infra-red beam "train detector" and relay that I'd recommend instead of isolated outer rail for detection if you go that route.   But me, I do it as described above.
