Elecrail Project

ELECRAIL project logo Ministry of Development logo Elecrail is a project that is defined as the systematic analysis of energy consumption on metropolitan, commuter and high-speed railway lines, with assessment of the energy impact and the economic result, including the development of models and simulators that can be adapted to different operating conditions by using different (measurable) parameters.

The current transport model, heavily dependent on oil products and non-renewable energy sources, is not sustainable from the energy and environmental point of view. Given that passenger transport is necessary, and considering that demand is expected to increase in parallel with economic growth, public authorities are making significant efforts to reduce the external dependencies of the transport system, especially those arising from energy use.

Therefore, Metro de Madrid and, in particular, its Control Centre Unit and the Rolling Stock Engineering Unit, participate in the ELECRAIL project together with 11 other companies. This project is subsidised by the Ministry of Public Works’ Centre for Public Works Studies and Experimentation (CEDEX, Centro de Estudios y Experimentación de Obras Públicas) and seeks to theoretically analyse, simulate, experimentally verify and economically assess the actions that need to be taken to reduce electric railway energy consumption.

The project is divided into six parts: General and common aspects, Vehicle characteristics, Electricity supply, Cogeneration, Storage and network design, Timetable and driving design, Application to High Speed lines and Metro and Commuter line Applications.

The project includes the development of simulation models that use quantifiable parameters for the analysis of consumption reduction strategies, the efficient design of railway timetables, the efficient design of speed regulation stages for application to the ATO (automatic driving) system on underground networks, and the design of optimal driving considering the regeneration of energy for other trains and the high-speed train network. The results of the simulation will be tested in two real cases, on the Madrid metro network and on a high-speed line, at the end of the project in December 2009.

The project will also involve developing electric models to which different values will be assigned in order to evaluate the impact of the different strategies to be adopted when using different technologies and design criteria.
