43098 Walton Castle crosses the Huntspill River on 22 August 2023 with the late running 2U24 12:50 Penzance to Cardiff Central GWR service. This is a location that I have been meaning to visit for decades, but somehow never go around to. Although it is an easy spot to get to, being taken from a minor road overbridge, it does require concentration, as the train cannot be heard or seen until it appears at speed on the bridge!
