Hi - first of all, if it was you, I don't appreciate the complaint that led to me being blocked. I was on vacation and not checking OSM. 

I use both languages, so feel free to respond with whatever suits you best. The "designated timetable locations" fall into a category that doesn't quite fit with OSM's tagging scheme and I've noticed that using the "junction" tag is the convention that the community in North America seems to have settled into. These are the operating locations that appear in railway employee timetables, which are mostly private, though there are some public avenues to obtain this information. Also sometimes referred to as "controlled locations" or "control points" or "station name signs" or, colloquially, a "plant." They are not stations, and should absolutely not be conflated with them, and there aren't any other tags in the OSM database that quite match up to how they are used - "junction" is the best fit, since they often are in fact junctions. It also has the bonus of making them show up more prominently on Open Railway Map, where the information is most desired. 

With respect to the node I added in Lorette, it's the precise location of the station name sign marking the designated location of Lorette at mile 152.4 of the Trois-Rivières subdivision, and is meant to be separate from the nearby "locality" node. 

With that being said, if you think there's a more appropriate designation for these that I may have overlooked, I'm willing to hear it. I admittedly have mostly been concentrating on obvious errors and omitted information, and haven't yet taken the time to go further in depth with tagging.
