West Coast refurbishment In December 2019, all 56 trains transferred to Avanti West Coast, operators of the new West Coast Partnership. A major interior refurbishment of the fleet commenced in 2021, involving the replacement of all carpeting and standard-class seats, installation of power sockets at every seat, provision of more luggage space in second class, refitting of the onboard shop, installation of new lighting, and the reupholstering of existing seats in first and standard premium classes. Additionally, one first-class coach in each of the 35 eleven-car 390/1 units is being converted to standard class in order to provide additional capacity. The refurbishment programme is stated to cost £117 million and is expected to run until 2024, with the work being performed by Alstom at Widnes in Cheshire. The first of the refurbished units returned to service on 25 April 2022. Fleet details Liveries All units were delivered in Virgin Trains livery of silver bodysides with black areas around the windows, red roofs and red cab-sides with the red areas on the cabs separated from the silver with a curved white band. Doors were originally painted with grey and white stripes. These were re-vinyled in plain grey in 2015. From September 2017 onwards, the fleet was repainted by Alstom in Widnes into a new livery known as "Flowing Silk", featuring plain white bodysides, black roofs and a vinyl applied red swoosh around the driving cab intended to visually represent a moving piece of silk. The livery was designed to use neutral colours at the behest of the Department for Transport to allow for an easier rebranding. The first unit to wear this livery was 390010. All of the nine-car units were repainted with last to be treated in August 2018, with repaints then commencing on the eleven-car units. The final unit to receive the full Flowing Silk livery in August 2019. Subsequent repaints omitted all Virgin branding in preparation for the end of the franchise in December 2019. Names All 53 of the original units were given cast nameplates in a standard style bearing the word Pendolino on the top of each name although several units were subsequently renamed with similar replacement cast nameplates being fitted. New cast names were applied to the additional four units after they had initially entered service without names. Cast nameplates were removed from each unit when they were repainted into 'Flowing Silk' in 2017-18, and
