Thank you.
From a lawyer's perspective, anything that's loose or requires some subjective requirements leads to litigation and expense. There's no definition of “operational”. When you deal with operational, you may exclude inadvertently other service terms, things like force majeure or other things that would be part of a standard contract.
Operational requirements have been referred to already by members of this panel. If you look at what a railway's operational requirements are to others, you're moving the focus away from you as the shipper to other scenarios, and that's going to become an evidentiary issue as well.
