CASE STUDY

ETCS National Integration Facility/ RIDC Melton

Overview of Deliverables

Network Rail wishes to undertake First in Class and Driver Confidence running of ETCS enabled vehicles at the RIDC Melton (RIDCM) test track, whilst leveraging the laboratory/technical assets available at the ERTMS National Integration Facility (ENIF).

ETCS lineside and laboratory assets are being supplied by Infrasig, in order to enable testing at RIDC. Infrasig requested Vertex to utilise their background knowledge of ENIF Operations (Vertex having supplied the Safety Case to enable ENIF Operations on the Hertford Loop and subsequent amendments to enable L3 Hybrid, COMPASS and multiple-vehicle operations) in order to demonstrate safe operation of demonstrations at RIDCM whilst ‘controlled’ from ENIF.

Vertex provided a Safety Case Addendum to Infrasig, in order to enable testing to be conducted from ENIF, with vehicles operating on RIDCM infrastructure. This Safety Case Addendum is to be submitted to a NR SRP in order to gain approval for ETCS testing to commence at RIDC.

Deliverables Included

  • Analysis of existing ENIF Safety Case and Hazard Log to determine any changes to risk profile;
  • Production of a Safety Case Addendum to provide evidence that proposed testing at RIDCM can be safely conducted from the ENIF facility without detriment to existing ENIF activities, subject to the identified Safety Requirements

Technical competencies applied in the delivery of the contract

Vertex employed the following competencies during these works

  • Systems Engineering – appreciating the impact of the proposed solution as a system, and determining its impact on existing systems
  • Safety Engineering – identification of potential hazards and potential mitigations.

Value added initiatives

Vertex utilised its extensive knowledge of the existing ENIF suite of safety documents in order to minimise the amount of rework required. This included interrogating the existing Hazard Log in order to extract relevant hazards.

Programme start and completion dates

Approx. March-November 2020

Resources utilised

Vertex utilised its team of Railway Systems Engineers and Project Managers for this project. All team members had previous experience in developing safety documentation for ENIF over the past 5 years.
