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!
The oil derek's power pole can no longer be deconstructed but still can be interacted otherwise -- i.e., it can be mouse-hovered and even clicked. However, the on-hover tooltip lacks the entity name (Unkown key: "entity-name.or_pole"). I am using Russian locale if this does matter.
