Class 365 ETCS Installation Mass Analysis

for Alstom

Alstom asked DB ESG to undertake a mass, kinetic envelope and brake assessment of Class 365 electric multiple units. This was necessary because of the fitment of European Train Control System (ETCS).

Work Undertaken:

  • Design assessment, including: -
    • Review of the vehicle changes.
    • Generation of a mass change spreadsheet, to collate the changes and understand the effect on the vehicle centre of gravity.
    • Calculations and assessment of change on vehicle movements, braking and derailment.
    • Risk assessment of the change
  • Changes and effects summarised in a final report.
  • A gauging review concerning the new equipment installed, namely the underframe and roof mounted equipment.
