They are, yes. The same style as GWR so rough rather than soft, but hopefully at least look better than the flat cloth.
Interesting. But unfortunately somewhat too little too late, given that the flat cloth has now been fitted across all Desiro units, the rebuilt 458s, some 158/9s and the brand new Arterio's. Perhaps, given the length of time taken to get them into service, the Arterio's will need new cushions regardless!
Still, I don't understand First Group's aversion to traditional Moquette. At least that works, was easier to clean and keep soft. One reason why I prefer the 158s and 159/1s which retain the SWT interiors.
