Need info on Vicksburg Southern & other Watco lines

i am looking for info on the following Watco owned shortlines; mission mountain railroad, mississippi southern railroad, and vicksburg southern railroad. i checked watco's website but other than it showing map locations, it did not really give much info on locomotives used on those 3 shortlines or what companies they serve, or what they haul.

You might want to try this link: http://watcocompanies.com/railroads.htm

Hope this helps ...
