I understand that the train is running anyway and stopping at all stations, like a Shabbos elevator. A Shabbos elevator runs anyway, continuously. You simply walk in when the door closes and it stops at all floors until you get to you floor and you walk out.

Hence, kosher cruises. The ship/ train is going there anyway, and you are doing nothing to promote it's movement... you are simply along for the ride.

There is also a Chofetz Chaim precedent.
