With the introduction of Permanent Hazards Railroad crossings and Cameras have been moved into the Permanent Hazard menu. It would now make (a lot of) sense to also apply this to the chart layers, to prevent people from wondering why railroad crossings or cameras are greyed out in the menu while they do have the permanent hazard layers checked on. It should be similar to how the Places layer has been restructured.

Unless it will be merged into the hazards layer of course, then this is redundant.
