Objectives

CONNECTA-2 aims at contributing to the Shift2Rail’s next generation of TCMS architectures and components, combining the new drive-by-data concept for train control together with wireless information transmissions. This project envisions paving the way towards a 50% increase in the availability of trains related to the functioning of train control and monitoring, a 50% reduction in cost, time and effort in certification, commissioning and maintenance phases, while at the same time developing the ability to implement SIL4 functions in the TCMS and supporting the development of the “virtual coupling” concept, which can dramatically increase the capacity of lines.
The high level objective of the work is to continue the activities started in CONNECTA-1 to bring the technologies to TRL5 and deploying them in two laboratory demonstrators. The specific actions to be undertaken within the scope of CONNECTA-2 contributing to the above high level targets are: 
  • To continue the development of wireless technologies for the train communication networks, including the wireless ECN, the wireless ETB, the train-to-ground communication and the train-to-train communication.
  • To implement the new train-wide communication network (known as NG-TCN) for full TCMS support including the replacement of train lines, connecting safety functions up to SIL4 and support of “fail-safe” and “fail-tolerant” principles, to provide an optimal train network for TCMS and OMTS (Onboard Multimedia and Telematic Services) as well as communication mean for non-TCMS functions, as defined in CONNECTA-1.
  • To continue with the standardisation of functional interfaces of functions (application profiles).
  • To implement the Functional Open Coupling (FOC) concept to facilitate the coupling of two or more consists supplied by different manufacturers and which could have different train functions.
  • To develop the simulation framework, defined by CONNECTA-1, in which all subsystems of the train can be simulated, allowing remote and distributed testing including hardware in-the-loop through heterogeneous communication networks.
  • To implement the Functional Distribution Framework (FDF) to allow the new function-centric approach for the TCMS and the reduction of the number of onboard electronics and of complexity.
  • To integrate into the NG-TCN safety critical functions.
  • To validate non-railway standards and technologies for use in safety-related railway applications.

Project Structure



WP1 - General Specification and updated requirements definition

The main objective of this WP will be the specification of new technologies needed for the rest of technical WPs of the project. Theses specification will define the technologies to be implemented and integrated in the urban and/or regional demonstrators.
From these technologies, some of the non-railway specific ones are expected to be implemented and provided by the complementary action (S2R-OC-IP1-01-2018).
The specific objectives of WP1 to:

  • Specify the evolution of Wireless TCMS, including T2G, WLTB and WLCN.
  • Define new Application Profiles for TCMS functions using the methodology defined in Connecta-1.
  • Extend the FDF requirements defined in Connecta-1 with the experience obtained in the implementation phase within the WP3 of this project.
  • Definition of functions for DMI for standardisation.
  • Completion of Function Open Coupling regarding the input and output needed for DMI visualization.


WP2 - Deployment of transversal technologies and analysis of new technologies

The main goal of this WP is to implement the evolved T2G specify in WP1 and the Application Profiles which will run on top of the FDF deployed in demonstrators. For T2G implementation members of the project will implement new functions of the IEC 61375-2-6 not implemented in Connecta-1. Later on, members will be expected to participate together in interoperability tests to be carried out in the laboratory and the demonstrator. Additionally, in this WP, members will work together with the X2Rail-1 project in order to extend the IEC 61375-2-6 architecture to the “Adaptable Communication” concept coming from that project in order to allow reusing the radio carriers used by signalling applications by TCMS T2G applications.
The specific objective of WP2 are:
  • Implement the rest of the functions of the IEC 61375-2-6 which have not been tested in Connecta-1.
  • Implement the extended Network Selector function of IEC 61375-2-6 to be interoperable with the “Adaptable Communication” concept coming from the X2Rail-1 project (S2R-CFM-IP2-01-2015).
  • Implement alone and together with the complementary action (S2R-OC-IP1-01-2018) different Application profiles to run on top of the FDFs deployed in WP3.


WP3 - Technical specification and implementation of components for lab demonstrators

This WP shall specify the laboratory demonstrators for an urban and a regional train application based on technologies developed in Connecta-1 and Roll2Rail. These specifications shall consider:
  • CTA1-WP2-Wireless TCMS, Train-to-ground communication and WLTB interoperability
  • CTA1-WP3-Drive-by-Data, proof-of-concept for safe train inauguration with consists from two different partners (interoperability test)
  • CTA1-WP3-Drive-by-Data, interconnecting safety functions (e.g. onboard signalling components and/or brake-by-wire) and non-safety functions with unique train communication network using the network technologies defined in CTA1.
  • CTA1-WP4-Functional Distribution Architecture, functional interoperability based on a functional distribution framework and application profiles
  • CTA1-WP4-Functional Open Coupling, deploying application profiles in train wide communication
  • CTA1-WP6-Simulation Framework and Train Virtualization, use of virtualization and validation of tools and architectures


WP4 - Test definition for lab demonstrators

The main objective of this WP is the specification of test scenarios and test cases for demonstrating the correctness integration of technologies and architectures defined in Connecta-1and Roll2Rail. These test specifications will be done for both, the urban and the regional demonstrators.
The specific objectives of WP4 are:
  • The definition of test cases and lab setup to test the Wireless TCMS, including train-to-ground, WLTB and WLCN.
  • The definition of test cases and lab setup to test the Drive-by-data defined in Connecta-1.
  • The definition of test cases and lab setup to test the Functional Distributed Framework.
  • The definition of test cases and lab setup to test the Application profiles for HVAC, BMS and/or Doors running on top of the Functional Distributed Framework.
  • The definition of test cases and test scenarios for Functional Open Coupling functionality.
  • The definition of test cases and test scenarios for Virtual Homologation Framework.


WP5 - Implementation and test execution in urban lab demonstrator

The WP will aim at integrating technologies developed in Connecta-1 and Roll2Rail in the urban demonstrator. This demonstrator should be the basis for the future validation and later deployment on real vehicles. It will ensure technical and functional interoperability of technologies and architectures from different suppliers defined in the following Connecta-1 work packages:
  • Wireless Train Backbone and Train-to-Ground communications Drive-by-data
  • Functional Distribution Framework
  • Application Profiles
  • Virtual Homologation Framework


WP6 - Implementation and test execution in regional lab demonstrator

This WP seeks to integrate technologies developed in Connecta-1 and Roll2Rail in a regional lab environment. This demonstrator should be the basis for the future validation and later deployment on real vehicles. It will ensure technical and functional interoperability of technologies and architectures from different suppliers defined in the following Connecta-1 work packages:
  • Train-to-Ground communication
  • Drive-by-data + integration of onboard signalling components and/or brake-by-wire
  • Functional Distribution Framework + integration of 3rd party function (OC)
  • Functional Open Coupling (optional)
  • Application Profiles
  • Wireless TCMS (regional with support of OC)
  • Virtual Homologation Framework


WP7 - Dissemination and Exploitation

This WP seeks to ensure proper dissemination and promotion of the project results, in a way which is consistent with the wider dissemination and promotion activities of Shift2Rail. It will ensure that the outputs of the project are delivered in a form which makes them immediately available for use by the complementary action (S2R-OC-IP1-01-2018) and further activities within the initiative.
It will also ensure that all important actors in the European railway sector are informed about the results. In that sense, an additional and crucial objective is to facilitate acceptance of the project outcomes through the standards and regulatory bodies, as well as by the main actors of the European railway sector.
