Editorial interest 76/100 Selection signal · not a rating of the site

A French-language prototype for exploring estimated Paris Metro train positions, service regularity, and a time-shifted network view.

Landing page captured for the 2026-09-28 issue.

For: Paris Metro riders exploring service and train movements
Worth noticing: The map is schematic and train positions are explicitly estimates, not GPS; the prototype cites Île-de-France Mobilités PRIM / ODbL.

Field notes

The interface separates network-wide, line, and station views, with controls for live mode and historical offsets from five minutes to yesterday. It labels the map as schematic and stations as official, while train locations are estimates rather than GPS. The page says the historical record is still being assembled; connecting a PRIM key is an available step, and it says that key remains only in local server memory.
