1. Usually, train tickets may be more reliable when they are not nervous. It's not reliable when it's tight Because it is a ticket purchase, it is not immediate, so you can't know immediately if you buy a ticket. Sometimes it takes two days to tell you that you didn't buy a ticket, which delays your trip and is unreliable.

2. These ticketing websites need to be insured, which increases the financial burden of ticket buyers.

3. There is a risk of revealing personally identifiable information.

Good luck!
