When you place a question into an existing thread, it can be confusing. This is the original thread - http://forum.allaboutcircuits.com/showthread.php?t=17300.

Several questions come to mind, but let's start with the most important - Is this for a model railroad or full size?

 

What are your specifications for the project?

What gates do you want to control? When they have to open/close?

What are the information the system has to look as to change automatically the rail tracks?

What is your knowledge on electronics?
