Heathrow Express 332 Drags (Old Oak Common - Greenford Loop/Triangle)?

[SteamontheMet]

Hello Everyone,

Apologies if been mentioned before.
Today as I was coming out work today (Tesco Hoover, Perivale) at roughly 17:30 I saw a EWS/DBS Class 66 (didn't catch the No) pass with a Heathrow Express (HeX) set between a set of barrier wagons head down the Ex GWR Mainline/New North Mainline towards Old Oak Common from the Greenford Triangle.

I had heard about such moves but for possible Tyre turnings?
Couldn't find anything online apart from this video which is now roughly two month old.

Anyone know about them or have times for this spectacle?

The units are or were being refurbished. Could this be it?
