LGV南東線
A large refurbishment project of the Paris Austerlitz is currently under way. Four new platforms are being constructed and all the existing tracks are being refurbished. The interior will be rebuilt in order to handle LGV Sud-Est and LGV Atlantique services, partially transferred from the Gare de Lyon and Gare Montparnasse, both of which are at maximum capacity. All the work is planned to be completed by 2020, and will double the activity at the station.
