Expanding worldwide, the automatic metro have technology which calls important safety tests. To meet this need, SPHEREA launches its offer of the dynamic test bench.


Automated transit systems are picking up momentum across the world. They offer a relevant solution for the city of tomorrow because they make it possible to increase traffic density while reducing the cost of operating the lines. However, with no operator on board, the tests carried out on each train after maintenance operations are particularly complex — to the extent that systematictrack tests are required. The test tracks, which cover tens of thousands of square meters in urban areas, represent a significant land cost and are a source of noise pollution or those who live and work near the facilities.

Lille led the way in automated underground trains in the 1980s and now has two lines of rubber-tyred light automated vehicles. To help absorb the increased traffic on its lines, the operator of the Lille metro will soon double the length of the trains. This increase in the number of trains has a knock-on effect on maintenance operations and the current test track will not be able to absorb the volume of tests. Moreover, there is not enough land available to accommodate a second track.
