Wish I could use the PS4 Second Screen App on my iPad to show and interact with different instrument panels onboard the locomotive. Anyone from Dovetail who could give a reply if this will be possible in a future update?
In order to do it you need to download a different app from the app store in order it to work type in ps4 remote play in the search bar
Remote play and second screen are not the same thing, they are very different indeed. Remote play allows you to use your console as a whole from a seperate supported device. Second screen takes certain aspects of gameplay and throws them over to said second device, increasing "immersion" and gameplay opportunities... one of the earliest examples I can think of is one of old F1 games, it allowed your phone, or vita (RIP) to act as a wing mirror, or track map. TSW could benefit from this greatly, but as its all ports from the pc version, with very little attention being paid to the specifics of the consoles its being launched on, I doubt they'd take advantage of console specific features.
