The railway from Paris to Marseille is an 862-kilometre long railway line, that connects Paris to the southern port city of Marseille, France, via Dijon and Lyon. The railway was opened in several stages between 1847 and 1856, when the final section through Lyon was opened. The opening of the LGV Sud-Est high speed line from Paris to Lyon in 1981, the LGV Rhône-Alpes in 1992 and the LGV Méditerranée in 2001 has decreased its importance for passenger traffic.

The LGV Sud-Est is a French high-speed rail line which connects the Paris and Lyon areas. It was France's first high-speed rail line. The inauguration of the first section between Saint-Florentin and Sathonay-Camp by President François Mitterrand on 22 September 1981 marked the beginning of the re-invigoration of French passenger rail service.
