Resum:
Since the opening of the TGV-Atlantique in 1989, the maximum speed on a commercial operation has been in Europe of 300 km/h. In Japan, the mentioned level of performance was reached in 1997.
However, the new line Madrid-Barcelona has been projected to allow maximum speeds of up to 350 km/h. This decision has not been motivated by the wish of breaking a record. It has been simply the consequence of a commercial need: reach a journey time of 2h15 between both cities, located at a distance of 680 km. Only with this level of performance it will be possible to obtain a market share of 60% with respect to the airplane, justifying, at least partially, the investment done on railway.
In this context, the current paper has a double purpose: the first, to expound, within the actual state of the knowledge, the theoretical reflections carried out to have a track and a vehicle the most suitable possible to the mentioned speed of 350 km/h; the second, to show the results obtained during the tests at 350 km/h, regarding track vertical and transversal loads.
The conclusions deduced from the research accomplished show that, with the measures adopted for the track and vehicle, it will not be expected a relevant increase on the maintenance costs of the Madrid-Barcelona line, compared to the ones found on the Madrid-Sevilla high speed line.
