Adds massive cargo ships to the game, that function similarly to trains. Also adds tanker ships, train bridges. NOTE: In 2.1, You Must Install Oil Rigs Separately!
Make sure you can select the ship engine at the back (and open the fuel/schedule dialog). If this doesn't work, then the ship was placed incorrectly. You have to pick it up and put it back down on a longer section of waterway.
Move the inserters closer to the ship. They need to be the same distance from the waterway as they would be to a train rail (this is a game engine limitation unfortunately).
