TECHNICAL ASPECTS OF HIGH-SPEED TRAINS. TRACK AND ITS INFRASTRUCTURE. ELECTRIC INSTALLATIONS

L'ASPECT TECHNIQUE DES GRANDES VITESSES. LA VOIE ET LES INSTALLATIONS ELECTRIQUES DES LIGNES A GRANDE VITESSE

Two-part paper states that the problems raised by trains traveling at 260-300 km/h are related essentially to vehicle operating stability and track stability, and have been substantially solved at the present time. Without going into the details of calculations, these problems are discussed along with the results of theoretical studies and tests. The techniques and approaches used can, for the most part, be regarded as operational today. The speed of the wheel-rail system is certainly not limited to 300 km/h: faster trains would raise economic as well as technical problems. In spite of the efforts made to raise speeds on existing lines, it is not possible to exceed 200 km/h on these lines, owing to the infrastructure which dates back to the last century, except on short stretches where high-speed tests have been conducted. The design of the infrastructure and superstructure (track, signaling and catenaries) of new allowable train speeds of 300 km/h is described in the article along with the engineering studies which have been making increasingly greater use of data processing techniques.
