For those with the good fortune to not be a regular MML user, Twitter/X this morning has a photo of a particularly egregious example of the 222's condition, that a couple of well-known rail journalists have commented on.
The image in the tweet linked below is of the seat cushions of 2 seats on an East Midlands Railway Cl222, taken from above. The seat covers are red, dating from the Stagecoach/EMT refurbishment around 2008. On the aisle seat, the seat cover has torn away at the front edge, and it appears that the exposed cushion foam has also been torn away. The seat cushions on both window and aisle seats are heavily stained, and the metal table edge also shows ground-in dirt/staining.
