Gare Montparnasse, officially Paris-Montparnasse, one of the six large Paris railway termini, is located in the 14th and 15th arrondissements.
The station opened in 1840, was rebuilt in 1852 and relocated in 1969 to a new station just south of the original location – where subsequently the prominent Montparnasse Tower was constructed. It is a central element to the Montparnasse area. The original station is noted for the Montparnasse derailment, where a steam train crashed through the station in 1895, an event captured in widely known photographs – and reproduced in full scale in several locations.The station serves intercity TGV trains to the west and southwest of France including Tours, Bordeaux, Rennes and Nantes, and suburban and regional services on the Transilien Paris – Montparnasse routes.
