John B, The bulk of the signal mast logic systems have aspects that refer to the turnout as part of the aspect. Generally labeled diverging and usually another word of two like diverging approach or diverging slow. Physically using a dwarf combined with a high mast is not something in most if not any of the systems. Can you roll your own, yes. But that's a lot more work. Also that high and dwarf combo would not be something immediately understood by most operators. Generally the rule systems expect that you have a mast with one or more heads to display the appearance of the aspects. Never on two different physical devices. But maybe somebody can provide a prototype example. -Ken Cameron, Member JMRI Dev Team
