I have to say that at least visually the Mallard refurbishment certainly improved the interior environment (can't comment on seat comfort), I mean what's going on with all those glass(?) partitions throughout the carriage!?
What's wrong with the glass partitions, I thought they were one of the funkiest bits of the mark 4 interior.
As for the seats, they were
very badly worn by the time the Mallard refurb was instigated, and I always thought they were much too thin, and too hard, for an Intercity train. In Intercity days the appearance wasn't too bad, but by the time GNER were holding the reins and the seat moquette had completely faded there was very little visual impact to be had from the interior of a mark 4. The Mallard refurbishment is a big improvement all round.
That "railfaneurope" site has really brought back the memories. I
knew I could remember mixed formation IC/GNER liveried mark 4 rakes at the start of privatisation, but hadn’t been able to find any photos to prove it.
