Class 321 Demonstrator


The Class 321 Demonstrator is the second investment Eversholt Rail has made to demonstrate the benefits of refurbishing existing rolling stock. The Demonstrator shows how high-specification refurbishment and technology upgrades to the existing fleet of Class 321 EMUs can compare favourably with the passenger experience and performance of new trains, at a significantly lower cost, providing:
  • A more modern environment and a “new train” feel
  • An enhanced passenger experience
  • Flexible interior layout – Metro or Suburban
  • Options for increased capacity

The Demonstrator will operate in normal service for one year on the Abellio Greater Anglia route and we will be inviting both industry stakeholders and passengers to give us feedback on the range of options exhibited through our online survey.

A further project to fit a new traction system to increase traction performance and energy efficiency to that of a new train is being developed and will be fitted to the Demonstrator in 12 months.

Project Build

Work on the Demonstrator was carried out at Wabtec Rail in Doncaster and took 12 months to build.
