I have started to automate my M track layout with CS3+ and focused on use of contact tracks instead of (finnicky) toggle tracks. The latter sometimes get stuck and wagons with lighting sliders complicate the trigger. I have not tried reed switches on my layout.
I discovered after many crashes that the standard m track contact rail (5105 and 5104) has an isolated length that is less than the wheel distance of my modern trains (like ICE). Sometimes it senses occupancy, sometimes not. I can use a contact extension track and two 1/2 railroad crossing trigger tracks, but that is a lot of specialty track for one sensing segment (and hard to find, and expensive).
Is there a clever way to make one's own contact segments with M rail? I experimented with cutting rail, but it remains grounded to the metal base regardless.
Some cutting and soldering is fine. Suggesties, Marklin fans?
