There are two provisions in the Railway Safety Act for rules. There's section 19, which is for cases when the regulator orders the railway to develop a rule. There will be a timeframe and certain parameters that they have to meet; then they will file the rule with us, and the minister will approve the rule. Also, there's section 20, which allows the railways to develop rules on their own initiative, which they will file with the minister and the minister will approve. So in either case, the minister approves the rule.
The distinction between rules and regulations is that regulations apply to all railways, whereas some railways may have specific rules that apply only to them. Generally speaking, what we're trying to do is to have rules that uniformly apply to all railways, because it's becoming really hard for us to follow.
