They had quite a substantial refurbishment in 2017/18: Rail passengers in Norfolk, Suffolk and Cambridgeshire are to benefit from cleaner, smarter trains with more seats and plug points, as Greater Anglia’s first refurbished Class 170 trains re-enters passenger service. 170 270 is the first train to receive a complete overhaul and now features plug sockets, refurbished seats with new cushions, backs and covers, new carpets, new flooring in the toilets, refurbished heating, ventilation and air conditioning systems, new wall panels, repainted vestibules, grab handles and grab rails, a deep clean throughout and a new livery in Greater Anglia colours. The work was carried out by Arriva Traincare at their facility in Crewe under contract to Porterbrook Leasing who are investing £5 million into the upgrade of Greater Anglia’s eight three-carriage and four two-carriage trains which operate on routes including the Norwich to Cambridge, Ipswich to Cambridge, Ipswich to Lowestoft and Norwich to Lowestoft lines. Every three-carriage train will also have six more seats installed. The project is expected to be completed in early 2018.
