Phosphate Trains?

[uspscsx]

I hear a lot about phosphate trains and I see a few of them come through every once in a while. I would like to model one (CSX) and need help. What type of covered hoppers do they usually use? Any photos? Generally, how long are the trains? Any specific weathering patterns? Any help is greatly appreciated.

Thanks in advance.

These might help, although they are of Chessie cars. It'll be the 7th post in the thread. http://www.railroadforums.com/forum/showthread.php?t=9509

If you're interested, Funaro & Camerlengo makes models of the Seaboard cars. The appear to be nice models.

We have potash trains coming to our port city all the time. Is that close enough?
