The only thing I would add is that what we mean by the words that we say is important. A huge part of service is capacity, meaning how many crews, how many locomotives, how many places are needed for that service to be most optimally balanced to meet network needs.
That's the biggest question mark right now. We just don't know what the railways' actual capacity is. When we ask them questions about this, they tend to say they're making record investments back into the network, that $1.5 billion, 20% of their revenue, is going back in. It seems like a lot, but in reality we don't know whether that's sufficient. We have no idea whether it needs to be $2 billion or whether it's more than enough.
