As I said earlier, a lot of progress has been made on the regulatory framework and our oversight posture, but we know there's more work to do. We are moving forward with an update to the railway safety management system regulations in order to solidify and codify the effectiveness approach into regulation.
We're also moving forward with enhanced train control, which will address the risks around signals that colleagues from the Transportation Safety Board spoke about. We're advancing some of the technological pieces, such as the piece around automatic parking brakes. It is a TSB recommendation to move forward with automatic parking brakes. It's still in the prototype stage for freight railway. We're doing research now with the National Research Council and other partners to help push and nudge that technology forward. That's ongoing.
