Biggest rail ferries?

These two ferries of CG railway are possibly the biggest rail ferries in world, they operate between Alabama and Mexico, carrying as much as 110 cars per ship in two levels.
see : http://www.cgrailway.com/ and go to Media for pictures.
anyone know of any bigger operations ??

I can imagine that loading and unloading that has got to be very nerve wracking! Wonder how they keep it from listing a lot when they load and pull?
Thats a lot of cars!
