On bank holiday monday I saw a full length HST trundle through Barnes
station
going north. What would it have been doing on Southern region?

Reading is closed. What you saw was a divert from the west country.
Normal route to Westbury then reverse and down to Salisbury, Basingstoke,
Addlestone, Brentford to get in to the "correct" side of Waterloo. Going
back they use Richmond instead of Barnes. From Bristol/Swansea they route
to Oxford, Banbury (reverse) then down through High Wycombe to Paddington
