Signalization tests for the upcoming T10 tram line will take place from October 7 to October 9 in Vénissieux, a commune in the Rhône department of France. The tests will occur during three consecutive nights—on Wednesday, October 7; Thursday, October 8; and Friday, October 9—at Vénissieux station. These operations will begin at 9:30 PM and continue until the end of the night's service. The tests are focused on new switches installed both north and south of the station on the tracks currently used by the T4 tram line. These switches will eventually connect the existing T4 line to the new T10 line. During the tests, the teams will evaluate several key functions, including the movement of the switches, the detection of their positions, and the transmission of information to the monitoring systems. These checks are essential to ensure the switches operate correctly and safely. As a result of these tests, there will be adjustments to the T4 tram's circulation starting at 9:30 PM each night. These changes are expected to be temporary and will not affect the overall service for passengers during the day. The TCL, which manages the tram network in the Lyon metropolitan area, has opted to conduct these tests at night to minimize disruptions for passengers. By carrying out these operations during off-peak hours, the TCL aims to reduce the impact on daily commuters and maintain the reliability of the existing T4 line. This phase of testing is a crucial step in the development of the T10 line, ensuring that all technical systems are fully operational and safe before they are officially put into service. The T10 line is part of a broader effort to expand and modernize public transportation in the region. Once completed, the T10 will provide a new connection between different parts of the metropolitan area, improving accessibility and reducing traffic congestion. These signalization tests are an important milestone in bringing the project closer to its full implementation.
