The LGV Picardie is a proposed French high-speed rail line running between Paris and Calais, via Amiens, in Northern France.
The SNCF decided instead to build the new high-speed line on a more direct route between Paris and Lille.
The Picardy region is now served by the TGV Haute Picardie station, though this has been criticised for its lack of intermodal connections, summarised by the saying, la gare des betteraves ("station in a beetroot field").
[1] The LGV Picardie would presumably deviate from the existing line north of the Gare du Nord and proceed directly to a new junction with the Calais branch of the LGV Nord to the east of Calais-Fréthun station.
The French government has announced their SNIT future investment plans that are to be built by 2030, and for the first time [2] the LGV Picardie is now included for implementation between 2020 and 2030, a project to cost €4.8bn, via either Amiens or Rouen.
