Mark 3 refurbishment for East Anglia services.

This refurbishment for Abellio seems sensible and economical. New seat covers, carpets, retention toilets and LED lighting are about all that is needed. Whilst mark 3 stock will always have its shortcomings, these minor improvements will put this stock streets ahead, in terms of comfort, of anything else on Britain's main lines, existing or proposed. The programme is for the upgrading of 119 mark 3 vehicles, mostly about thirty years old.
