Viewed from the footpath crossing at Grove, 800010 Paddington Bear & 800016 heads towards London on 20 September 2021 with the 1A14 09:30 Bristol Temple Meads to Paddington GWR service. I'm not sure whether the DMU's engines are still running, or if there is heat coming from the traction motors, but something is creating heat haze to impair the distant view of 66561, which is waiting on the up relief line with the 4L36 07:39 Wentloog to Felixstowe North freightliner.
