As new trains are getting the new PIS system, I think some of the older trains should get it to, I think rush hour is the perfect opportunity to do this with the existing trains that are included, it will definitely capture the Rush Hour feel
What "new PIS system"? As far as I'm aware and as far as i've heard the trains' PIS is the same as always, either Auto or Manual. Newer releases more Auto, older more Manual.
So the train-PIS? If so I'd say "no" to this. I prefer the manual operation of it, more realistic. This is really a backstep from the old system
An PIS Update would be really nice, but still I prefer on setting the PIS screen manually, but there are a lot of lines that have to get added on the PIS screen and also some trains like the Br143 and Br1442 also don't have a PIS screen so they could update these trains and add the PIS screen on them
