This is probably not a fair question to put to you, but given that there may be deficiencies in the efficacy of the detection of track defects, but in some cases, should there be rail relocations if you can't provide the assurance, particularly where there's dangerous cargo, and heavy cargo, and long trains going along these lines? Given that we don't know for sure that the inspections are catching the defects, should we be looking to other solutions to make sure that we don't have disasters?
