Gameplay Pis At Stations

How do I get my trains to be displayed on the passenger information systems at the platform?

 

So when you set your instructions there is something which should mean they show. I may be wrong on that though. Reason for this is I don't know if it's limited to just Train PIS or the station PIS.

 

I got this, but does not show on station PIS

 

not sure then.
