Thank you for the question.
Rail, from a safety and security perspective, is a highly regulated environment. There are multiple pieces of legislation with dozens of different regulations that layer upon railways' various expectations, requirements and obligations for safety and security. These range from track conditions to equipment, brakes and operating parameters and protocols.
As the regulator, our role is not to deliver for the railway companies on their regulatory obligations. We send inspectors to the field to make sure that they're meeting their obligations.
