Lyon extends integrated transport

The first two lines of the Lyon tramway system, operated by local public transit authority TCL and totalling 20km in length, are controlled using ethernet and web serving technology.

The first two lines of the Lyon tramway system, operated by local public transit authority TCL and totalling 20km in length, have been officially inaugurated. Less expensive than a subway, the tram lines expand TCL’s network, which includes a subway system, buses and funiculars.

To control the tramway, TCL selected a Schneider Electric remote control and monitoring solution, comprising 65 Modicon/Telemecanique Premium TSX PLCs equipped with an ethernet coupler and a web server for the new lines. The entire system communicates with the control centre via a fibre optic ring.

The main selling points that won the contract for the company in late 1999 were the web server function, which had already proved a hit with the subway owner and operator, and the OPC server for exchanges between PLCs and the supervisor.
