I'll just add very quickly, Tom.
As a qualified locomotive engineer myself, having operated trains for the last four years at CP, I can definitely see the value in terms of the inward-facing and outward-facing cameras. Part of our railway technology group, which I lead, does derailments and incident investigations, so having that video information is critical, not only to solving the issue but preventing it altogether. This plays hand in hand with the technology we've added in terms of data analytics, where we're actually auditing the event recorders on board for operators' actions. If you tie that to the video, it becomes very powerful in terms of ensuring compliance.
