Was largely a commuter service. Unfortunate part was that it was built over existing freight rail so mainly suburban stations with big parking lots that can be out of the way (and have to side to let prioritized freight pass, but new tracks have largely eliminated that). Pre-Covid, often at full capacity during morning/evening rushes and never “sold out”, you could always stand if you couldn’t get a seat. And flexible as no scheduled/reserved tickets. Credit card tap on/off is very new (last 12 months maybe). Nice that they have bathrooms on every car (looking at you Paris RER!!!).
