Extra baggage on G-train

Hello, for normal passengers, the height of carry-on baggage allowance is 20 kg, so you may take your hand carry with you. Since the luggage rack of G Train is too small for luggage in large sizes, you can have your big luggage be checked and transferred by freight.

How much will the freight cost for a 30kg bag? Will it travel on the same train or on a different one? When would it arrive if it travels on a different train?

Thank you!

Will be on a different train, arrives much later, for the price you'd better ask the staff at the station.
