Great. Thank you.
I'll go back to VIA Rail again. Obviously, with the security market nowadays, there's a host of products, programs, and systems available to choose from. When you're making decisions about the suite of security programs and security measures that you buy or integrate into your system, at even the smallest of levels, how do you go about making those decisions? Are they evidence-based, operationally appropriate decisions, keeping in mind sound financial management, or do you just try to invest in everything going and see what works?
