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!
Currently oil rigs are powered by steam engines and accept 2 modules. However, the steam engine doesn't generate enough power to run for instance speed module 3.
A possible solution could be to use steam turbines instead or just remove the module slots altogether.
