This is my first track layout attempt after diving back into 12V trains.
About this creation
This circuit uses 146 tracks, 4 switches, 2 crossings, 7740 & 7745 trains and 7822 (extended) & 7824 stations.
What is special about this track is that both trains can run endlessly without ever running into each other. Train paths can also be swapped with one button-press which will command all 4 switches.
Notice both tracks running adjacent inside the extended 7822 station. The only way to connect two tracks through switches while having them run adjacent is to connect a horizontal section of one track with a vertical section of the other.
