We provide our rail service through a third party called Bombardier. They do both the operations and the maintenance. We ensured that they did speak to their union so they would understand what our intentions were.
We have yet to use them to manage the crews. That's not a method that we would choose to use. What we have them there for is to understand how incidents happen and to identify the role of the operating crew should an incident happen where we suspect their behaviour may have some cause in the accident.
