Shunting signal

[mamochan]

I am reading through the wikipedia article on Japanese signals which was mentioned in a prvious thread and I am trying to grasp how the shunting signal fits into things.  I keep reading it and I just don't get it.  I am interested in it because I am planning on modelling freight operations and passenger traffic.  To do this I know I would need to model the signals.  especially since I plan to automate the passenger lines.

Shunting signals are used within yard or station limits, and are for the control of non-revenue movements (out of service trains in the case of passenger stock).  Trains are restricted to 45km/h (25km/h through unprotected turnouts/points).

I think I am getting a picture of how they are used.  From what I can tell the piece I was missing is that they are used with turnouts that are controlled automatically, as you described.  Correct me If I am wrong, In a modeling sense the loco enginner would contact the tower and request a route(press the button) then the tower(JMRI) would throw the switches and show the shunt signal and the engineer could proceed forward.

Yes, that's how I read it.
