I apologize in advance for the basic question. I just purchased Train Sim World 3 standard edition for PS4 for my son for Christmas. He also wanted the Harlem Line expansion so we bought that. However, when he loads the game there is nowhere for him to access the Harlem Line (or any of the other routes that came with the bundle). Does he have to complete scenarios to "unlock" the Harlem line routes and other routes or are we just looking in the wrong location? Currently there aren't any scenarios available beyond the training. He completed the 4 training modules and does not appear to be able to do anything other than the 4 training modules. The "quick play" buttons appear to be locked - he cant select either the 0-30 or the 30+, and the "Choose a route" and "rail journeys" both only list the "training center" as an option. And the "Train Depot - pick a train" gives 0/0 timetable and 0/0 scenarios and 4/4 training modules as options. Appreciate the help.
It sounds like you haven't downloaded the routes, go to the game page on the psn store, and see what add ons are available for free download.
Following on from the other answer. Press the stat button on your controller over the tsw icon and select manage content. Anything you bought will be listed here and available for install or delete.
