Channel Royal Train prog

Who does the research?
It starts off by saying the most elusive 'LOCOMOTIVE' and then said that only three people can use it
HMQ DoE and PoW with Camilla.
I am sure that Princess Anne has used it as well, but will stand to be corrected

Only 5min into it so expecting some other gems

AARgh the locomotive word was used again

Piss poor. bad research and writing spoilt the whole thing

Watched a few minutes of it. Went out. Not impressed!

Which channel was it on?

Sorry
IIRC it was either C4 or C5 certainly on catch up if you want to see abysmal continuity and 'Oh here's a film of a train lets use it'
