Quick question: Shall I still get refund if I missed the train and I purchased the eticket from the station agent? How could Amtrak find me?Well that's not exactly correct either.Those not scanned simply get accounted for as if they are no shows.
Depending on various circumstances, Amtrak can auto-recognize revenue. That means that all tickets will show as collected, even if one actually did miss the train. When that does happen, and you've missed the train for some reason, it can make things a lot of fun trying to get your refund or credit to new reservation.
