I would just like to add something to that. If we want the public transit system to be as extensive as possible, we have to be aware of all the available sidings and spurs. That's why we want to remove the words that refer to metropolitan areas. That is perfectly consistent with what we were saying earlier.
If you were to propose that it be linked to public passenger service, it would then be up to railway companies to decide whether these sidings can be used for passenger service. If they believe that to be impossible, they won't put them on the list. So, it would be better to keep the general reference. That way, we will know about all available sidings and spurs. That way, urban transit authorities and provincial governments will be able to decide to use these sidings and spurs if they so desire. In any case, there cannot be that many of them. If there are, it would useful for us to know about them.
