When the train station sign says „Gare de Lyon“, you’re not in Lyon. If you were, you’d read either Lyon Perrache or Lyon Part-Dieu. But Gare de Lyon means you’re in Paris.
So, welcome to the second-biggest Paris train station after Gare du Nord. Gare de Lyon has two main halls, Hall 1 and Hall 2, with platforms named A, (no B), C, D… in Hall 1 and numbered starting with 13 in Hall 2.
The Gare de Lyon is, like all other train stations in Paris, a terminus. Its high-speed trains (TGV) serve the southeast of France, the Mediterranean coast, and the neighboring countries: Spain, Switzerland, and Italy. Regional trains (Transilien) serve the southeast of the greater Paris area, and two RER lines run below the station, RER A and RER D, as well as the metro lines 1 and 14.

Located on the upper floor, the legendary Second Empire-style restaurant Le Train Bleu is a listed historical monument.
The Gare de Lyon is located in the 12th arrondissement, and you can reach its nearest neighbor, the Gare d’Austerlitz (change here for trains to Orléans, Bordeaux, Toulouse, and Nantes), on foot by crossing the Seine on the Charles de Gaulle bridge (approximately 10 minutes’ walk).
