It wouldn´t show yellow alone. It would be yellow+green, meaning "Proceed with caution" or go slowly ahead. |

Yellow means procede with caution with a green signal also. They won't be lit with an all red signal. Red with white means switching manuever allowed, and can be lit along with a yellow/green distant signal. The newest digital signals from Marklin have matching decoders that toggle them.

If it’s e.g. a signal with one ”plus” cable, and additional cables for ”red”, ”green” and ”yellow”, you could solve this using two switches: One for switching between ”red” and ”green”, and one for switching between ”yellow” and ”nothing”. If you’re digital, you may use two addresses on a k84 or m84 decoder, or a specific signal decoder, instead. When running digital under a PC software like TrainController, the software controls both the trains and the three aspects of the signal - ”red”, ”green” and ”green/yellow” - within defined rules. I have signals (on switchyards) that are wired to show only two aspects, ”red” and ”green/yellow”, i.e. they require only one digital address. |
