There is an interesting distinction here. Some set up signals that are very much intended to accurately reflect and model real train signals. Others set up signals to communicate to the model train operator the status of parts of the layout to avoid accidents. These layout signals may or may not represent real railroad signals. I have built many floor layouts in my life, some across multiple rooms. I have used signals to indicate the status of switches and blocks in the other room and they probably don’t replicate real railroad signals. There may be a third type of toy layout where signals are placed randomly for decoration and have no relation to real or layout signals.
T4TT that is a very ambitious layout build.
