• Add Rail in the Movement group, off by default: live trains from 30 keyless operator feeds in the United States, Canada, Australia, Ireland, Finland, Spain, Norway, Malaysia, Japan and France, from commuter and long-distance rail to the streetcars and trams of Seattle, Cincinnati, Toyama, Bordeaux and Montpellier. A new /api/rail proxy fetches registered feeds only, needs no key and drops buses from mixed feeds. Every train shown is live: 29 feeds publish GPS positions and Irish Rail its station reports, and 28 of them show with no setup. No train is placed or moved from a timetable; a feed whose live positions fail shows as unavailable. Packs are an opt-in extra: node scripts/build-rail-paths.mjs --feed <id> (or --all) builds a feed's path and schedule packs into .cache/rail-paths/, which add the operator's own route lines, stop names, the next stop and trip-update delays to its live trains; Renfe long and medium distance and KTMB, whose vehicles name no route, appear once their pack is built. Nothing is downloaded when the app starts, and lines are only ever the operator's own shapes. Trains are coloured by category (urban, local, regional, national, international), each with a chip and legend entry shared via token 02, glide between reports with Transit's delayed playback, are drawn once when several feeds carry them, and open a card on click. A selected train that is moving is followed by the camera, as an aircraft is, and any other is flown to once; the selected train and its line stay on the map from orbit. No train is placed in Ukraine. Feeds that publish no licence are used on the basis each one's entry records, and their credit never presents that as a licence (Denis Groshev, @ZloyS, #1675).
