It make sense for goods that sending them by air is too expensive, but they are too time sensitive to send them by ship. It takes a day by plane, 14 days by train, 45 days by the ship. I would expect in good scenario that train would be somewhat similar popular as air, but nowhere near close volume as by sea.
