Mr. Brockmeyer, I just have one more minute. You mentioned that public-private partnerships are usually about buying capabilities. They're not really—or they shouldn't be—about securing financing or these other factors. We talk about risk transfer.
When it comes to buying capabilities, are there other procurement models that allow you to secure the capabilities of the private sector while retaining public ownership and public operation of the service? Does your firm work on publicly operated and publicly owned rail projects in Europe and bring your capability to those projects so that they can tap into the innovation you bring?
