Between stations Cleunay and train Station, the structural work is also completed. “The other stations have suffered a little of late following the collapse of the floor in the store Noz in November, which resulted in a shutdown of the tunnel boring machine for 4 and a half months , “says Xavier Tirel. In the northern part of the line,
the viaduct between the stations, Beaulieu and ViaSilva is expected to be completed in the summer of 2018. “In total, we are almost two-thirds of this enormous construction site “, says the director general of the Semtcar.
The two trains have already been delivered are waiting to be tested
Assembly at the Siemens factory in Vienna in Austria, the first train of the CityVal arrived at the garage-workshop in the month of June, followed by a second two weeks ago. A third train is then expected to arrive in late November, Britain and the delivery will then continue at the rate of two trains per month.
For the first trains, the time of the first tests will soon be ringing. Static assays will first be conducted by the end of the year, before dynamic tests scheduled for later in 2018. The new metro will then be able to travel a distance of 300 meters in the garage-workshop. Testing will then continue for a distance of 1.4 kilometres between the garage workshop and the future station La Courrouze. “There will be at least two years of testing on the trains,” stresses Xavier Tirel.
