Resolves as YES if there is strong evidence that a new high‑speed rail (LGV‑type) corridor crossing central Paris north–south, enabling through high‑speed trains between Bordeaux and Lille without a change of trains, will be completed and open to passenger service before January 1st 2050.

More detail on what counts:

• The corridor must be purpose‑built or substantially rebuilt for intercity high‑speed passenger trains (TGV or successors), not just for metro/RER/commuter services. Lower speeds in the tight central section are fine as long as the line is clearly part of the national high‑speed network.

• It must cross central Paris roughly north–south and include at least one station that clearly serves the city centre (for example an underground or surface station at/near Châtelet–Les Halles, Gare du Nord, or an equivalent central hub).

• The infrastructure must connect the high‑speed network on:

  • the southwest / Atlantic side (e.g. Bordeaux–Saint‑Jean or its successor via LGV Atlantique or successor), and

  • the north / northern Europe side (e.g. Lille–Europe / Lille–Flandres or successors via LGV Nord or successor),
    such that high‑speed trains can run continuously across Paris on this corridor.
    
    

For this market to resolve YES, by the time it resolves there must be clear public evidence that:

1. The line is complete and either:

   • already in regular passenger service, or

   • has an officially announced opening date within a few months that is clearly before 2050‑01‑01;

2. At least one scheduled, bookable high‑speed passenger service is planned or operating that runs from a major Bordeaux high‑speed station to a major Lille high‑speed station without requiring passengers to change trains, using this north–south corridor (intermediate stops, including at the central Paris station, are allowed); and

3. Official maps, technical descriptions or operator documents identify the line as part of the high‑speed (LGV) network.
   
   

Peripheral LGV links or bypasses that do not provide a new north–south crossing of central Paris with a central station (for example, outer‑suburban interconnection lines that route around Paris) do not count for this market.

The market resolves NO if, once it is reasonable to judge shortly after January 1st 2050, there is no such corridor meeting all of the above criteria, or if earlier candidate projects have clearly been cancelled, indefinitely shelved, or radically redesigned so they no longer provide a central north–south high‑speed crossing that enables direct Bordeaux–Lille trips.

In close or ambiguous cases, the market creator will rely on the balance of evidence from official government and infrastructure‑manager documents, operator timetables, and expert consensus to determine whether the criteria are satisfied.
