Thank you.
This is more of a comment, and you can tell me if I'm on the right track or not. As I read your legislation, it refers to amendments to the Railway Safety Act. In fairness, this is the way the act reads, “If a railway safety inspector is of the opinion that the standard of construction or maintenance of a line work or railway equipment of a company poses a threat to safe railway operations”. You've added the words “or to the safety of persons or property”.
It would seem that the first definition is pretty general. It's hard to say what it exactly includes, but you've specified it particularly to be sure that it does include the safety of persons or property. It really is a clarification. It has a specificity to it so that we all know what it means and can take action if that is in question.
