-1 hall sensor ​should be positioned ​on both sides of both rail separation cuts., with a distance so,\\ +Hall sensors ​should be positioned ​at each side of both rail separation cuts., with a distance so,\\ 
-that hall sensor ​is activated BEFORE first wheels are approaching ​the rail cuts.\\ +that one of these hall sensors ​is activated BEFORE first wheels are touching ​the rail cuts.\\ 
- +H1 and H2 are positioned at both sides of separation cut left,\\ 
 +H3 and H4 are positioned at both sides of the other separation.\\ 
 +Simple tip: 
 +If you experience ALWAYS a short cut when train is running into the loop, there are 2 simple solutions:​\\ 
 +     * 1. swap the rail connections between the loop rails and GCA102. 
 +     * 2. swap H1 with H3, and swap H2 with H4.\\ 
 +One of these will be your solution.\\
