Thank you for the question. This is a very important matter.
Technology is a key part of safety going forward. We know that. A reference was made to train control technology, so that's something that we're advancing. These would be regulations that would compel railway companies to have smart driver-assist technologies in trains, so we're advancing on that.
There's another technology initiative under way in the department to advance what is called an automatic parking brake. This would be an automatic backup brake on trains. That's something else we're looking at.
Our role as the regulator is to ensure that whatever technologies do come online are safe and enhance safety. We can provide a level of assurance that whatever technologies are being brought in and being advanced by industry and others improve safety in rail.
