(05 Mar 2013, 8:47 pm)Brandon wrote I can't comment if any others have been treated, but one of Northern's Class 156 sets has been internally refurbished. The grey bulky seats have been replaced with less bulky seats with a smart purple trimming. There is much more leg room, but despite thinner seats being used, it seems as though seating capacity has been somewhat reduced.
If I'd thought on I would have got a photo and ID of the train set. Will try next time
Didn't get a photo of the interior, but did of the exterior. A poor photo, so it didn't go on my Flickr which is now incorporating train photos (if anyone had noticed!), but can be viewed on the attachment below.
