In order to do what you want to do you are going to have to script it out. You might take a look at the demo tracks that come with the game as one of them has programmed mode operations that feature switches that activate based on trains passing over them.

So I did that and Couldn't find any scripts if you could help me find the scripts that would be great.

Hope this will come out right!
