I don't like the term "Mk5".
It suggests someone has centrally designed a standard loco-hauled coach for which multiple uses will be found.
If ordered, they will just be a unique class for the TOC concerned, like the Caledonian Sleepers were.
Even Mk4 only turned out to be one order.
I know what you mean, but as far as I'm aware the Caledonian Sleeper order has been referred to officially as Mk5s. Technically they should really be mk6s as Mk5 was used (iirc) for both the cancelled IC250 project and for the Nightstar stock!
