Code for Basic 3-Color Signal (SN110) – Chapter 2, page 19
This code expands on SN095, by adding multiple LEDs/incandescent bulbs using the delay command to simulate the transition of a railroad signal through its sequence from red to yellow and back to green after a switch initiates the start.

Automatic reversing loop control for standard DC (SN184) – Chapter 4, page 44
This code senses when a train is in the reverse loop section and then throws the turnout along with swapping the feed wires to the main line so the train runs continuously with no action for the engineer.
