TE02 Enabler 2


Absolute safe train positioning (TRL5/6) – Absolute Safe Train Positioning solutions with more accurate position and speed, which will provide possibilities of optimising headway as well as energy train control assistance (ATO), allowing energy saving and densification of trains (+30%) with less trackside equipment. It focuses on the development of modular and scalable absolute safe train positioning system with incorporating new sensors.

Work Packages

Currently available work packages:

WP21 Absolute Safe Train Positioning (ASTP) - operational needs

The challenge of this activity is to provide Absolute Safe Train Positioning solutions with more accurate position and speed, which will provide possibilities of optimising headway as well as energy train control assistance (ATO), allowing energy saving and densification of trains (+30%) with less trackside equipment. ASTP will reduce maintenance costs and improve availability within equivalent safety considerations. ASTP focuses on the development of modular and scalable absolute safe train positioning system. It serves all CCS (and non-CCS) functions such as ATP, ATO, ATS/TMS, TCMS, applications of RU in train (e.g., DAS or travel-information) or on trackside. Then ASTP system should be scalable for different Safety Integrity Levels to cover the wide range of applications from low cost to high end resolution applications. Addressing the targets above, this work package deals with following objectives:
  1. Identify common high-level user needs and system capabilities of ASTP. 
  2. Analysis of required system performance for the ASTP system. 
  3. The TRL level associated to the documents produced in this WP is 6. When available, public results from other European initiatives like CLUG/CLUG2 will be considered in the frame of FP2-R2DATO for the Absolute Safe Train Positioning activities: those inputs will be evaluated and integrated when commonly agreed by this WP.

WP22 Absolute Safe Train Positioning - System Architecture, Design & RAMS

Absolute Safe Train Positioning systems designed in this framework shall provide train location and kinematic data (speed, acceleration) to address each and/or all the use cases from operational context listed in WP21. First steps in mastering safety of the solutions shall also be addressed. This work package complements the goals of WP21 and delivers following added value: 
  1. Definition of a ASTP system architecture and its design in order to reach TRL 6-7, also covering external interfaces, testing, and validations procedures. The work shall also cover safety evidence, including the interaction with the digital map server (e.g., transmission through FRMCS to the Onboard incl. version check). 
  2. The testing of the developed ASTP solutions. 
  3. General assessment and evaluation of ASTP solutions, as well as the impact analysis of ASTP with regard to TSI gaps, need for TSI CSS modifications.

WP42 Tramway autonomous movements in depot demonstrator

Identify use cases to be implemented in the second demonstrator, development, implementation, and validation through a specific demonstrator in Oslo. The objective of this third work package is to implement an AUTONOMOUS MOVEMENTS demonstrator up to TRL6.

WP43 Freight Demonstrator

To allow a smooth deployment of GoA 4 technology with different possible technological solutions, the systems need to be tested in real conditions in a demonstrator. The freight demonstrator will be equipped with sub-systems studied in the Technical Enablers. Tests will be performed, enhancing autonomous freight train operations.

WP46 Regional line demonstrations

The main objective of this WP is to provide the bridge between FP2-R2DATO and FA6 demonstrations by supporting validation and testing of technical enablers in regional line environment before they are handed over to FA6 for further adaptation and integration. The improved CCS and automation functions will be the main technologies tested and validated, building on the activities already performed in the scope of Shift2Rail ATO (up to GoA4) tests (the very same line and vehicle). Further, the line will be used to support development process of technical enablers, even on lower TRL levels, due to simplified operational environment and flexible demonstrations planning (no regular commercial service, the line fully dedicated to tests) and approval process. Minimal set of technical enablers needed: 

  1. Automating functions 
  2. ATO 
  3. Perception systems 
  4. Digital register
  5. Absolute safe-train positioning
