I have two big bags and two carry on bags. Are the big bags check at the station just like when

Usually it is not recommended to make them as checked luggage. If you are traveling with a high speed ride, the luggage will surely be arranged on other rides. So your luggage may reach the destination much later than you do. Usually the station is not too strict with the luggage weight. You can try to take them luggages with you to enter the carriage directly.
