How many peices of luggage are you allowed to carry on to the G trains?

Each passenger is allowed to take a certain amount of carry-on baggage for free.
A child is admitted to take luggages no more than 10 kg (22 pounds), 35 kg (77 pounds) for a diplomat and 20 kg (44 pounds) for an adult. Besides, the total length of each item cannot exceed 130 cm and rod-shaped baggage should not exceed 180 cm in length.
However, the luggage rack of G Train is too small for luggage in large or super sizes. There is no special rack or room for the large luggage either. If you have large luggage, you may not carry it onto the G Trains. Go to the trains stations earlier to have your large luggage be checked and transferred by freight, and pick up it when you arrive at your destination.
