Adds massive cargo ships to the game, that function similarly to trains. Also adds deep sea oil, oil platforms, tanker ships, train bridges and other water based content.
i am not sure i understand. are you joining two tank ships into a single train? that this is possible at all is a bug/limitation of the mods mechanics and is not intended behavior.
(with the newest version of the mod, ships don't get connected automatically anymore when placed close to each other, but its still possible to join them by hand).
