Discussions About Cargo Ships

Hi Ya'll,
I am completely confused. I bought my first ship without reading all the details. I don't have any idea where it went but I'll find it.
Is there a thread that explains it all in detail, like do I need large Bodies of Water and if I do, where do I get it?
Do I need a Port? Where do I get that?
Do I need the Freight Containers and where do I get those? Are they interchangeable with the Trains?
If you could just point me in the direction of specific details, that would be wonderful!
Thank You,
Sheera
