I'm really not getting all the excitement about an inaccurate historical repaint, especially when you apply the wider context.
Apparently DfT is all over the TOCs controlling everything they spend, yet there's the thick end of £50k spent on an un-needed repaint. Then add in that SWR's loing-suffering customers are enduring short formations (4 vice 10 in some cases), yet this unit can be spared for a couple of weeks or so to be repainted. There's some priorities that are very, very wrong in the organisation.
