Running 104 minutes late, Harry Needle Rail 37405 passes Grove on 13 January 2023 with the 6Z38 09:27 Swindon Transfer to Hinksey, conveying three Rail Head Treatment Train sets. This had worked up to Swindon with just one RHTT set, as the 6Z37 06:37 Bristol St Philips Marsh HST Depot to Swindon Transfer, and after leaving the train in Hinksey Yard, would continue north later as the 0Z38 12:45 Hinksey to Coleham light engine.
