Although relatively modern and well within their design life, the trains need work in the medium term to ensure the continued reliability of the traction control equipment and maintain fleet serviceability until renewal, which is expected between 2028 and 2032.
Selvom de er relativt moderne og er midt i deres forventede levetid, behøver togene renovering på mellemlangt sigt for at sikre fortsat pålidelighed i traction control-udstyret og vedholde vognparkens brugbarhed indtil fornyelsen, der forventes mellem 2028 og 2032.
