The electrification of the European railways is progressing with around half of the network already upgraded. However, the supply and modality of the use of energy in rail can have a huge impact on cross border traffic, notably because of the different electrification structures (AC or DC), and the different typology of rolling stock (pantograph head geometry). Rail Infrastructure Managers (IMs) invest in interoperability and energy efficiency according to the parameters set by the European Technical Specification for Interoperability (TSI) relating to the ‘energy’ subsystem of the rail system (Regulation (EU) No 1301/2014).  

EIM in action

  • EIM advocates an efficient, sustainable and cost-saving energy supply on the railway network;
  • EIM’s Energy Working Group (ENE WG) deals with the implementation of the energy legislation in the rail sector and the associated technical aspects; 
  • EIM also collaborates with other stakeholders to share information and to define joint positions. 

EIM actions in 2021 

  • EIM has been investigating in collaboration with other rail organisations how some energy related functions can be automated. A first enquiry was made with the experts in charge of energy (ENE) and command-control signalling (CCS), which may be extended to those in charge of locomotives and passenger rolling stock  (LOC&PAS). This investigation may result in a position paper and possibly in change requests to deliverables of other organisations;
  • EIM’s ENE WG initiated a discussion with the European Commission on the ‘minimum track access package’ and additional services for power supply. It also requested to change/update the relevant Regulation (EU) 2015/909;
  • EIM established a joint position with other stakeholders against the merger of the TSIs ENE (energy) and INF (infrastructure) as proposed in the Delegated Decision;
  • EIM’s ENE WG supported other EIM WGs regarding Vehicle Authorisation, electrical compatibility, energy measuring, route compatibility checks and the revision of the TSI on Safety in Railway Tunnels (SRT);
  • EIM’s ENE WG initiated a discussion with the ENE Steering Group of CER on electrical safety for third parties climbing on vehicles and approaching live overhead contact lines.
  • EIM’s ENE WG, together with CER’s ENE SG, submitted the Change Request on charging of battery trains, discussed existing change requests (CRs) and wrote “new” CRs, both regarding clarifications and “open points” in the TSI within the energy area. Interfaces with rolling stock and operation were treated within newly established Topical Working Groups and smaller Task Forces, e.g. on multiple pantograph operation and significance of renewal and upgrading for implementation plans. The WG made a proposal to improve the parameters of the RINF (register of infrastructure) regarding neutral sections.

Outlook 2022

  • EIM will be involved in the Energy Working Party of the EU Agency for Railways (ERA), which will apply the new Common and Control Management process set up by ERA. This Working Party will discuss the following change requests, e.g.:
    • Harmonisation of the structure of the interface requirements between the LOC&PAS and the ENE TSI (e.g. current at standstill);
    • Technical analysis of the provisions of the ENE TSI that could be relevant for upgrades and/or renewals of the ENE subsystem;
    • Setting of rules and requirements that could be considered for the design of the OCL (overhead contact lines) and the pantograph distribution in case of multiple pantograph operation (more than 2);
  • The EIM WG will continue contributing to the open points of the previous TSI ENE and tackle possible deficiencies to be amended or new improvements to be included the current text (e.g. battery trains).
