The main objectives of FUNDRES are:

• to define the future unified DC railway electrification including: 
• the study of the strategy for changing the railway electrification system from 1.5 kVDC or 3 kVDC to 9 kVDC; 
• the setting-up of Flexible DC Transmission System (FDCTS) concept which allow to implement a new DC line, interconnected with different AC lines by means of power electronics devices;
• the analysis of the integration in a common DC link that acts as an energy hub that collects the electricity production from the other sources (wind or solar) or the braking trains and deliver it to the connected loads, as the trains in traction phase or the charging infrastructures for electric vehicles. These common DC link can be realized at various voltage levels;
• to deliver modelling tools to simulate all scenarios and to implement Digital Twins, both at equipment level and system level;
• to set up representative experimental demonstration to evaluate performances of the future system;
• to give recommendation for the new future unified DC railway power supply to the project’s advisory group, to the members of Shift2rail’s Innovation Programme n°3, to standardisation committees.
