I've never been on a train. What are the steps by train? Is it the same as taking a bus? Is there a reminder before arriving at the station? Have you missed your stop?

It's similar to taking a long-distance bus at a passenger station. After buying the ticket, wait in the designated area after passing the security check. After getting on the bus, you will be assigned the corresponding seat. There will be a reminder when the train arrives at the station, informing each station of the station name and parking time. However, if the stop time is not long and you don't pay attention, it is still easy to miss the stop. Of course, if it is a train sleeper, a flight attendant will change the ticket in advance.
