Objective : transport 15’000 people per hour before and after every match.
- Equipment of the T3 line extension with railway signalling and overhead contact line to make this the most densely equipped section ever built, with 30 or so train positions across less than 600 m.
- Development of a complex, integrated solution to keep the intersection barrier system running smoothly all along the line. This highly effective tool improves traffic flow, both on the tram line and on the road.
- Development of 28 PLC programs with SIL2 safety level on a Siemens S7-315F PLC.
- Upgrading of the existing CTM system.
- Upgrading of the existing road intersection controllers. Development of a real-time simulation tool for the entire T3 line to validate and optimise the tram and road flow management system. This system incorporates the field environment, the characteristics of the different rolling stock (acceleration, braking, dimensions, etc.), the new PLCs, the CTM system, the intersection controllers and the existing manoeuvring areas.
- Replacement of 28 instrumentation and control cabinets on the line, each including a combined N.S1 relay/safety PLC.
- Installation of 200 axle counters.
- Continuity of line operation by adding 28 temporary signalling systems interfaced with the other subsystems (manoeuvring areas, road intersections, etc…).
- Prevention of technical risks : SIL2.
- Optimisation of road and rail traffic.
- Continuity of operation : work carried out while service is interrupted at night.
- Railway signalling : the most complex system in France to date.
