Availability, reliability and safety of our assets are the missions of mechanical operations. Siemens, like any one of our providers, is an important support to that availability and reliability. Since the December 10 incident, we've focused with them on engineering solutions and operational mitigations that we immediately put into place, and on ongoing software and hardware upgrades that immediately improved fleet reliability.
This is our focus for all of our fleet, whether it's a 50-year-old legacy car that's going to Vancouver or it's the new Venture fleet. We're accountable for the reliability of that fleet, and we'll continue to work with Siemens to push them, to pull them along, to make sure we reach that availability and to make sure we have the materials and everything we need to succeed for our clients.
