I just wanted to share that if you use JR Smart Signals (04, 06) and place a track direction marker facing towards you on the outside of an "OS" the signal will display a red over flashing red, it will do this regardless if the route is a diverging route or not. Also, if you use an JR Approach/Distant signal leading up to the absolute signal with the direction marker against you like i mentioned, it will display a Yellow over flashing red, which is appropriate. Just thought i'd share this as its a pretty effective way to set up a Restricting aspect, especially coming off a ML into a Yard or leading into dark territory.
