My opinion: this question fully justifies Hornby deciding to participate in the making of this series. Hornby, and RTR OO products generally, have clearly not been properly advertised to the potential market. Bachmann produced the first of their BR mk1 based MU's in 2009, twelve years ago (4CEP) and the reply from Hornby was the 4VEP, two or three years later.
(I skimmed episode 4 entirely, without detecting anything of enough interest to go back and watch!)
