Thing is though, you'd have to lay track yourself and buy a dedicated train/carriages to go with it.
Not exactly a cheap exercise. More importantly, its a time expensive exercise.

I did like the air freight for BGS better because they had to load/unload the trucks/trains about 5 times i think. This is due to the fact that Mali is isolated from the coast.
Maybe AVZ will only see 1 load/unload; on at the chem plant and off at the port.
