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!
There's a typo in the tooltip for the startup option 'Oil Rigs can be build before chemical science' (and in that phrase, now that I read it). The option should read 'Oil Rigs can be built before chemical science' and the tooltip has 'without' spelled as 'wihtout'.
