High-speed railway track construction is the process by which Lignes à Grande Vitesse (LGV, litt. "high-speed railway line"), the land on which TGV trains are to run, is prepared for their use, involving carving the track bed and laying the track.

The TGV (1981) was the world's second commercial and the fastest standard gauge high-speed train service, [16] after Japan's Shinkansen, which connected Tokyo and Osaka from 1 October 1964. It was a commercial success. A TGV test train holds the world speed record for conventional trains.

France has a large network of high-speed rail lines. As of June 2021, the French high-speed rail network comprises 2,800 km (1,740 mi) of tracks, [1] making it one of the largest in Europe and the world. As of early 2023, new lines are being constructed or planned.

TGV track, however, answers to stringent requirements that dictate materials, dimensions and tolerances. To begin laying track, a gantry crane that rides on rubber tires is used to lay down panels of prefabricated track. These are laid roughly in the location where one of the tracks will be built (all LGVs are double tracked).
