OSIRIS aims at enabling a reduction of the overall energy consumption within Europe’s urban rail systems of 10% compared to current levels by 2020.

In order to fulfill the objective above, the following specific objectives will be addressed:

* Define the overall needs and operational requirements allowing for the development of a global approach for the simulation, optimisation and benchmarking of the energy consumption of urban rail systems (i.e., Light Rail, Metro, Suburban);

* Define a series of standardised duty cycles and key performance indicators for urban rail systems to allow for direct performance comparisons and benchmarking of technologies;

* Develop a holistic model framework assembling existing proprietary traction and power network simulation modules into a complete urban rail system model (i.e., the OSIRIS tool). It will include all the primary parameters that influence energy consumption, as well as their inter-dependencies. As part of the project, a model of thermal energy exchanges within trains, tunnels and stations will be developed as well;

* Employ optimisation methodologies for the identification of efficient, reconciled strategies for realising low energy consuming urban rail systems, based on the use of the OSIRIS tool;

* Propose a Technical Recommendation (TecRec – a sector-wide voluntary standard) for the use of onboard energy storage systems, addressing the issue of assessment and mitigation of safety risks for the customer and operation staff;

* Evaluate specific railway technologies, operational strategies and the economic/political framework for the future reduction of energy consumption in urban rail systems;

* Assess and compare the overall energy saving potential when applying new technologies or operational modes; and implementing them over both existing and new equipment.

* Demonstrate energy savings through the OSIRIS tool and a number of defined demonstration scenarios based on real use cases.
