Gated on #210, #217 and #219.

railways ← N50 Bane (CC BY 4.0), with anleggstype (J = jernbane),
banestatus and sporantall (track count). Confirmed present in delivered GML.
stations ← N50 Stasjon, which carries navn (Alvdal, Bellingmo in
the sample) — named out of the box, unlike Denmark's. Entur's National Stop Register is
the urban half and the rung-ladder signal.
transit ← Entur aggregated GTFS and NeTEx, licence NLOD, plain
anonymous GET (verified HTTP 206 on
rb_norway-aggregated-gtfs.zip and rb_norway-aggregated-netex.zip on
storage.googleapis.com/marduk-production/outbound/). Covers the Oslo T-bane, the Oslo,
Trondheim and Bergen trams, and the funiculars.

The one thing to verify before building transit

GTFS shapes.txt geometry quality is unverified. The project has been burned here
before: semap's metro and tram lines were originally built from GTFS shapes, found to be
distorted, and rewritten onto Topo 10 ralstrafik survey geometry. Check Entur's shapes
against a known alignment before wiring them, and if they are distorted, look for survey
geometry (Kartverket N50 Bane may carry T-bane and tram as anleggstype values other
than J — enumerate that domain).

Note Entur's API docs ask consumers to identify with an ET-Client-Name header, but the
aggregated bulk zips download without it, so no provider is needed.
