Here you see 4 trains, 2 can run at the same time and 2 can stop at siding. 2 fast trains and 2 slow trains running from level 1 to level 2. A maximum of 12 ft can be fitted onto the siding. At the back is level 3 where you can see train nr 5.
I have now completed soldering wires all around the track direct from the controller this helps heavy trains to climb the steep incline. It now works well even without weights.
