Energy management is a key issue for railway systems and this situation will continue to be prominent for the foreseeable future. Multiple operational scenarios add complexity to the development of suitable and appropriate energy management solutions. Moreover, existing assessment tools lack an integrated approach, and tend to omit the variation in emission levels, energy usage and associated costs resulting from differing traffic peaks.

Given that the railway system is a complex and interconnected system, a single supplier, operator or infrastructure manager (as large as they may be) cannot tackle the energy management issue for the entire network alone. Hence, ONLY through a collaborative approach such as MERLIN can effective solutions for this issue be developed. Appropriately, the MERLIN consortium brings together the key rail stakeholders from across Europe.


In 36 months, MERLIN will deliver:

Issue of proposal for Technical Recommendations (UIC/UNIFE TecRec):

Future Business models & recommendations (smart energy management, cost saving):

Optimised solutions for current and future business models:

Numerical models and simulations to demonstrate the architecture developed for the above TecRec.


Where MERLIN’s results will be implemented, an overall reduction of the energy consumption of 10% is expected.


MERLIN will contribute to the EU’s aim of a more sustainable rail system and a reduction in CO2 via a more efficient use of energy resources.
