Osiris started on the 1st of January. Osiris will finish in December, 2014. Osiris has 17 project partners, including all major stakeholders: public transport operators, railway manufacturers and universities.

For many transport modes, energy reduction strategies can be effectively formulated at the level of the vehicle. New technologies can therefore be introduced to a vehicle and the direct energy savings can be readily quantified. However, this approach is not suitable for urban rail, where it is not sufficient to consider only the energy performance of vehicles; the energy associated with the infrastructure, as well as the influence of the mode of operation are to be considered too. In other words, urban rail systems are complex environments and their energy consumption is characterised by a wide range of inter-dependent factors. For example, whilst a new technology might yield improvements in certain respects, it might also compromise other aspects of system performance. This means that it is often extremely difficult to assess the net benefits of introducing new energy saving technologies.

OSIRIS is expected to bring positive benefits to the urban rail sector (i.e., operators and manufacturers), as well as to the community as a whole. These benefits can be summarised as follows:


* Energy and CO2 savings thanks to progress in real tested technologies and solutions.


* Common understanding with the manufacturers on energy savings and related innovative technologies (KPIs, duty cycles, TecRecs)

* Decision Support Tool methodology: selecting optimum combinations of technical and operational solutions

* Real experimental results from the field of innovative technologies to save energy  (RS, Infrastructure & operational measures / thermal & electric energy)


* Clearly defined and harmonised requirements by operators

* Extended electrical system simulations tools to integrate the new smart grid concept  and new thermal simulation tool

What is needed, and what has been lacking so far, is a holistic approach for the reduction of energy consumption for urban rail systems embracing vehicles, infrastructure and operation, as proposed by OSIRIS. The project will start from the definition of Key Performance Indicators and Standard Duty Cycles to measure energy consumption in urban rail systems. Then, rather than focusing only on specific technologies, it will address the issue from the system-level ensuring that progresses on energy reduction are substantial. The effectiveness of solutions and their full potential will be proven by simulations and pilot tests. OSIRIS will introduce the entire discovered knowledge into a Decision Support Tool, to aid strategic decision-making for companies (operators) and governments (public authorities).
