D1.2 – Energy Management & Pre-Standardisation for Alternative drive trains and related railway system Intermediate Report No 2

The present document constitutes the Deliverable D1.2 “Energy Management & Pre-Standardisation for Alternative drive trains and related railway system intermediate report n°2” in the framework of the Flagship Project FP4 – Rail4EARTH.
The activities carried out up to now within the FP4 WP1 led to the drafting of this second version of the document which reports the status of the SP3-WP1 of Rail4EARTH after 32 months of work on the different subtasks:
– Pre-standardisation of battery interfaces: ongoing, battery interfaces are identified and discussed between partners to propose standardised ones,
– Pre-standardisation of interfaces between train and operation: preliminary, state of the art of range operation calculation and first description of needs for operators to supervise alternative drives trains,
– Pre-standardisation of interfaces between train and infrastructure: ongoing, identification of standards impacts and requirements for battery train charging, parking energy supply, and hydrogen train refuelling,
– Pre-standardisation of energy management functions: ongoing, state of the art build commonly with RAIL4EARTH WP5 for energy management functions + definition of different strategies for charging of battery trains,
– Optimization of energy management at railway system level: ongoing, description of a methodology to compare use cases and scenarios from railway system view. Definition of a first use case in France and scenario with a 1st generation battery train, with the application of the methodology and the analysis of the results,
– Identification of standards to be adopted for the interfaces and components of trains with alternative drives and related infrastructure,
– Integration of the standards identified into the “Standardisation and TSI input plan” STIP of FP4-Rail4EARTH WP28.
As this Report is the second intermediate WP1 progress report, some works are still pending and will be finalized by the end 2026.
