Hello @semin
Thank you for your question.
You can find the information about the service luggage station to station on the following link: Station-to-station luggage | SBB. It takes normally 2 days to bring the luggage from a station to another, that means that if you send the luggage on the 25th of May, you will get it on the 27th of May.
I wish you a nice day.
Kind regards, Giorgia
