..."Of course the iron ore producers who want access to the QNS&L will contribute capex!".....


My understanding is that $$$$ put forward by project proponents as contributions to capital expenditures on things like rail and port are rebated in the form of reduced tarrifs  on a "per tonne moved" basis until such time that the contribution is entirely returned to the proponent.

Also understand that capacity reserved on QNS&L is " take or pay" - proponents pay the railway for the negotiated capacity starting at the negotiated start of contract date - even if the project has suffered slowdowns or setbacks and does not have product ready for shipment.
