The train section between Meiringen and Giswil, which is part of the Golden Pass line, is indeed interrupted on November 11. You'll have to travel by bus instead of train on this part of the route, which will make the total journey a bit longer. This also goes for regular trains. The replacing buses will perfectly connect to the trains, so you don't have to worry about that. If you still don't like the idea of having to change to a bus on your way to Lucerne, you can also travel from Thun to Lucerne using a direct route (via Olten).
In November the sun will set around 17:00, so the last part of the journey may be dusky already. To prevent this, you could indeed travel to Lucerne a bit earlier.
