If you buy a train ticket by credit card, the refund will be returned to the credit card account used for payment. This refund may not arrive in time, and refund information may be received after the refund, but in fact it usually takes about 3~5 days for the refund to arrive in the account. Some may arrive immediately after the refund. This time is specifically related to the bank. Generally, after receiving the account, you will receive a short message notice from the bank. You can always pay attention to SMS notification, or check the entrance of refund in the credit card official website.
