I know the frustration that was raised. I heard from railways and municipalities likewise in terms of the new tracks. In terms of when new track is laid and the issue of proximity of development--either in advance or where new development is going to occur--there needs to be a provision so that the municipalities become aware of the potential for conflict with the rail system, and the fact that the rail system is in many cases protected as a national priority.
