I'm on the refurbed 333013 this morning down Airedale. Rather a nice unit now, even if 3+2 Is less than ideal. Given the delay to the introduction of the longer 331s, these will do nicely in the meantime. Shame that they aren't putting charging points on the stock though!
But yes, bright, light and clean. Very nice, and the moquette looks good too. Now we just have to hope that Northern have a decent cleaning contractor (I'm not holding my breath) or these will start to look grubby very quickly!
EDIT: compared very favourably with the overcrowded and rather grubby 185 onward journey I can tell you.
