The way I look at category usage is "if pages will be tagged with it, make it a category". Like TT said, since storage doesn't really have any sub-pages (just a table really), it should be a normal page. Same goes for Local Slots, IT Slots, and Depot Slots.

On the other hand for example, Eras would be a good category under Extensions, then have the Era pages (Dieselisation, Electrification, Hyperloop) in there.
