Travel Times before and after the Introduction of a High Speed Train Service (hours)

The setting of high speed train systems has considerably improved travel time between several major metropolitan areas, on average a 50% reduction. In many cases (such as Paris / Lyon on the Paris / Marseille axis) the drop in travel time has placed new areas within commuting range. The high speed train system has also the advantage of servicing central areas (for most stations) implying an overall higher level of accessibility to the city. By including travel time to stations commonly well serviced by public transit, the high speed train system can compete effectively with short and medium distance air transport.
