Located on Boulevard de Vaugirard between the 14th and 15th arrondissements of Paris, Montparnasse Station, the fourth busiest in the capital is actually three stations in one. Porte Océane, the main section, faces Montparnasse Tower (and is located where the original 19th century Montparnasse Station once stood). It can be accessed on Avenue du Maine or directly from the metro.
Pasteur Station is located on the south of the platforms, while Vaugirard Station, south-west of Avenue Pasteur, serves a few suburban lines. The station, which historically connected Paris and Brittany, now serves much of western France, from Lower Normandy in the North to the Pyrénées in the South by way of the Centre and Charente regions. Night trains even link Paris 15 to Spain and Portugal, while cities in France are served by TER, Intercités and TGV Atlantique trains.
