Having a nosey at the re-building works at Reading Station at about 12.05pm today when I saw this "strange sight" in the distance. Turned out to be 47500 on the up relief with a set of WCRC Mk1 maroon stock with a green Mk2 BSK. Looked like the stock from yesterday's Royal Duchy. I assume it was returning to Southall from Bristol, not sure what it's next duty is though as nothing is shown on ukSteam & the RD runs again next Sunday. Shame there wasn't a steam loco involved though!
