Signalling work on line B of the Orléans tramway
In August 2024, ETF carried out signalling work on line B of the Orléans tramway, a line whose terminus, brought into service in 2012, serves a new residential area. The area was originally a wasteland. Infrastructure, including junctions between the tramway and the road, had been planned, but remained unused, blocked by concrete obstacles. With the urbanisation of the area, these junctions must now be put into service, which requires adjustments to signalling.
Teams from ETF’s Civil Engineering and Signalling agency moved a signal to prevent the stationary tram from blocking traffic. This involved creating two new track circuits to detect the presence of the tram and regulate the signalling. In addition, an interface was installed between the rail and road signals, so that the traffic lights turn red when the tram arrives. This work required the unwinding and wiring of new circuits in an external cabinet and in an existing signal box.
The work took place in a grassed area, in the heart of an ultra-urban environment. For three weeks, tram traffic was interrupted to allow work to be carried out on signalling, roads and traffic signals. This coordination between several participants and the management of complex interfaces ensured that the work was carried out smoothly.
