THE FRENCH RAILWAY SPEED RECORD
As part of a study of the technical and economic aspects of high-speed operation, the SNCF conducted four days of trial runs at progressively higher speeds. The purpose of the tests was to investigate the margin of safety allowed by the speeds now regularly scheduled with normal types of locomotives and rolling stock. They were also regarded as a contribution to research into methods of improving the productivity of transport and reducing its cost, by showing how the building of vehicles able to run at ever-increasing maximum speeds can reduce maintenance expenditure on locomotives and track when operating at the speeds now normally scheduled. The test train consisted of three coaches of a recent design. Continuous records were made on all the runs by means of piezo-electric apparatus of the lateral forces exerted on the track by the first and third axles of the locomotive bogies. It was found that these did not exceed 4.2 tons.
