Railcar sites

I am trying to get information about certain rollingstock including commodity it carries, destination etc. Is there a specific website I can go to to find this information out. Also, I went onto the yahoogroups and signed up. I am trying to join modelintermodal. Is anybody here a member of this site and if so, how long does it take to for new comers to enter it?

I know some railcar sites, dont know is these will help. www.krunk.org and www.railarc.com.

or you could try my site…http://www.freewebs.com/railine/index.htm
