The dwarf signal is used to indicate switch position and in yards. Because it is short, it is for low speed areas. Most place them near a switch and hook to the switch controller to change the aspect color. Through is green, Red is diverging. This is relative to your mainline path.
The tall signals are for main line use. They are for train speed control. Red is stop and wait for orders, yellow has different rules, but is like slow, proceed with caution and green is maximum speed for that area or by railroad rules.
Most will place a couple on the mainlines where visitors can see them to mimic traffic control. They are usually green when a train approaches a signal block, the train triggers the relay when it enters the block, then it turns red for time, then yellow, then green again when the train has cleared the block.
You can search them forum for threads on the ways to control the signals.
Carl !
Thank you !
