As some of you have requested bigger ships for transporting huge amounts of goods from one place to another, you may be interested on this article about the monster engines that move those kind of ships..

My favourite one is
Seiman's 340 MW Gas Turbine...
In addition to that, here you have the world's largest engine crankshaft, which I guess belongs to ship, too..Each cylinder has 7,000,000 cubic centimeters (7m3)!!

Is there any pakset in Simutrans that can host such an engines? perhaps pak1500? ::)
