In order to provide passenger back up service in case of failures in their Voyager or Pendolino fleet, Virgin Trains invested in a rake of Mk3 coaches and DVT stock so that if breakdowns or the need for an extra service was called for the Virgin Charter Relief Train could be called upon to provide the back up support needed. The motive power is provided by EWS which along with the coaching stock is the inspiration of this new Hornby Train Pack.
