Detector Rail

[LUF2K14]

Hi once more ...
recently in my peacefull map i decided to use trains but i barely know how to use lights to control so i thought '' what if was a detector rail like minecraft has?'' so thats why im requesting because i dont know C++ and i know that will be a huge script to do that with the logistic system because with that ican control where the trains are and when they will 'meet' in a 'rail-cross'

thanks in advance ...

Will two extra chain signals in row break your design? If not, just read the state of first one.
