This paper is aiming at qualifying the high speed trains in operation in France, with regards to spatial equity. To that end we begin by examining some of the various concepts enclosed in this polysemic word. Increased accessibility was one objective of the development of high speed rail. Thus we estimate a simple model to measure the possible effect of high speed rail on French regions. We did find a positive effect on GDP per capita and demographic growth. In a sense this is because they are growth-promoting that High speed lines are unfair. Beyond that, the pricing system set up by the train operator is based on yield management and intermodal competition. This results in a peculiar and singularly unfair pricing structure.
