APPRAISAL OF PREVIOUS HIGH SPEED TRIALS - PROVING AND PERFECTING PRE-PRODUCTION TRAINSETS

VALORISATION DES EXPERIMENTATIONS ANTERIEURES A GRANDE VITESSE. JUSTIFICATION ET MISE A PROFIT DES RAMES DE PRESERIE

The article gives details of the chronological order and the development of high speed rolling stock from February 1954, when the world railway speed record of 243 km/h was established with the production line CC 7121 locomotive, until 1972 with the delivery of the TGV 001 gas turbine train especially designed for high speed running which exceeded 300 km/h on many occasions, and the Z 7001 (1974) electric trainset. The authors describe the scope of the high speed trials carried out with four motive power units, TGS, TGV 001, RTG 01, all three being turbotrains, and the Z 7001 electric trainset, which together covered 1,079,533 km and performed 1,369 runs at over 250 km/h, and each made its contribution to the sum total of knowledge so that the future high speed stock for commercial service could be defined. The pre-production trains to be delivered in 1978 will enable existing knowledge to be completed and new factors to be tested, such as the behaviour of articulated 8-coach trains with a power car at both ends, running two trainsets together, aerodynamics and additional resistance to forward motion because of the equipment on the roof, 25 kV 50 Hz current collection conditions, perfecting the safety installations on the line, comfort, etc.
