Around a decade after privatisation, Class 153 DMU 153369 still bears a Regional Railways livery with Central Trains branding - from the earliest days of that franchise's operation.
As this is photographed at Bristol Temple Meads station, which has never been served by Central Trains, it is presumably now operated by Wessex Trains.
