Stored only in this browser (localStorage). Planes & Amtrak work without it.
MARC & Ride On show scheduled times with no setup (built in) — MARC trains are placed on the map from their schedule.
Planes overhead need a feed you run yourself — this board ships without one, because the free public feeds do not permit commercial use and we will not make that your problem. AIRCRAFT-FEED.md has a ready-made proxy and takes a few minutes on any small server. Leave this empty and the board simply runs without the aircraft card.
MARC on the map is scheduled by default (no setup). Only if you want the exact live
