Theyve had an age to sort this out, but with no one at the helm of GTR taking any lead (or basically not caring), and My Grayling himself not interested in running a railway, it seems no alterations to the spec have been done.
What say would GTR have had on interior layout? As a management contract, wouldn't the DfT have said the interior spec should remain the same (less toilets and first class)? Who would have paid? GTR? DfT? The ROSCO?
As with carnets not going onto a smartcard, it's not a DfT requirement so it just doesn't happen.
