3. Innovations and Optimisations
Innovations Innovations and Optimisations 1- Pre-cast trackbed 2- Pre-assemble track panel installed by trolley 3- Green Track Solution
Innovations and Optimisations Pre-cast trackbed Pre-cast track bed increases installation rate Minimize interfaces with other modes, such as cars and cycles on shared roads Limit traffic impact at junction areas or line interruption during track renewals Tramway T3 Paris (2002) Installation of precast trackbed at junctions areas Croydon (2010) Installation of precast trackbed for track renewals
Innovations and Optimisations Pre-cast trackbed Installation of pre-cast trackbed at junctions areas
Innovations and Optimisations Pre-assembled track panels installed by trolley Increase track installation rate Facilitate installation on street with limited access Main Reference: Grenoble Tramway
Innovations and Optimisations Green Track Solution Reduce drastically the construction materials Decrease Initial investment and Maintenance Cost Reduce irrigation water consumption Maintain a high degree of rigidity and cohesion with the ground
Innovations and Optimisations Green Track Solution Installation of precast elements Installation of rails into precast element recess
Innovations and Optimisations Green Track Solution Top soil filling After completion. Differences between green track solution and classic permanent way
Optimisations Innovations and Optimisations 1- Standardisation and Uniform Design 2- Improving capability of operators 3- Reducing the costs of utility diversions
Innovations and Optimisations Standardisation and Uniform Design Rationalise / Standardise design, operation and practices to reduce cost Uniformity across the country for future development How: Choosing rolling stock, components, equipment for stations from a standard range Using off-the-shelf information systems from existing bus systems Proposing simple designs for landscaping
Innovations and Optimisations Standardisation and Uniform Design Mats Example
Innovations and Optimisations Standardisation and Uniform Design Station Example
Innovations and Optimisations Standardisation and Uniform Design Joint procurement of Tram Vehicles Economy of scale Possible when the timetable for projects is similar Example : Brest - Dijon joint procurement
Innovations and Optimisations Improving capability of Operators Tramway operators to consider pooling maintenance facilities and expertise Maintenance depots becoming centers of expertise in a certain field Synergy for maintenance and repair strategies and processes Pooling of spare parts Shared ownership between operators of heavy maintenance equipment Greater sharing of expertise within the sector
Innovations and Optimisations Reducing the cost of utility diversions Tramway routes that run on highways/roads are often deemed to require the diversion of utilities (water and gas pipes, power cables) which are usually placed in roads and pavements Significant part of the cost of a scheme (10% of total investment cost) Objective : avoid diversion of utilities by using of a lighter weight track-bed consisting of: Pre-cast concrete strips under each rail (e.g. Green Track Solution) Embedded Track Solution (e.g. Precast track bed, Q-Track System )
Innovations and Optimisations Shallow trackbed Continuously supported embedded rail system Rail encapsulated for easy replacement and maintenance No Fasteners No Sleepers Shallow Trackbed 30-40cm only
Innovations and Optimisations Conclusion Tramway System is : Green / User Friendly / Urban developer / Cost effective Multiple ways to drive the cost further down : Optimisation of constructability to reduce construction time Reduce construction depth / minimise utility diversions Green for real Standardisation of design / maintenance Economy of scale
