Refurbishment of class 444/450 trains

How many of the class 444/450 trains have been internally refurbished? Less than half of them, half of them or over half of them?

  • No 444s have emerged from refurbishment yet. 444040 went in for one months ago, and it has never emerged...

    No 450 has received a full refurbishment either, although some have received part refurbs (new carpet and seat covers).

    It is much less than half of the 450s, I currently have 21 logged as being partly refurbished, out of a fleet of 127...
