Rail....say 1 mil per km
250km to run
2 year payback is 125 mill year
div 6 mill tonnes per year
= $20 tonne freight cost break even for capital
operating costs....$5 tonne thats a wild guess :)
$25 tonne + pofit (if mak invests then opex is reduced by profit portion)
= very good number as logistics portion of opex
