How to control manual streets wye.

Thanks L.J. You were very helpful. Your link to "How to control manual streets wye" is exactly a variation of what I'm trying to do. The thread proposed a number of potential solutions but none proven. The simplest is adding a return spring which maintains wye position. My guess is some light weight Super Street vehicles will have difficulty overcoming the spring force. The switch machine idea will work except you have to automate the machine set and reset. The best idea IMO is the spring loaded plunger solenoid. The wye will snap to the set position all by itself during normal operation. You can use automation/logic to control a spring loaded plunger solenoid to reset the wye position. Anyone have recommendations for small 14VAC spring loaded plunger type solenolds ? Can use Azatrax detectors to sense vehicle position and to provide the momentary solenoid command.
If I could plug Azatrax for a moment. Great products for the DIY folks and helpful beyond belief.
