How does using the same ticket work? I'll be transferring from train to tram. Could be buying through the app if I can figure out - otherwise will get paper tickets. If I do paper, I just hold onto the ticket and show it to an inspector if asked, or do I need to validate the ticket somehow on the tram? (Is it the standard 100 minute transfer?)
