In August 2022 I went to Dawlish one evening and met a Dutch student at Exeter St Davids, but on the train from there appeared to develop a joint injury (sudden arm/shoulder dislocation I believe) and wanted help to find a hospital. I searched for some places on Google Maps and suggested them near where she was going, before I had to leave at Dawlish as my ticket went no further. However she then got off and she was acting all confused.
After a short call to what sounded like a relative, she then asked me for help to get back to Bath, where she was a student. This subject Gloucester train was the next one, so told her to get this and change at Bristol Temple Meads for a service calling at Bath Spa, it came in and I got her on it quickly (it was running late and understandably the guard was in a hurry), but she looked a bit panicked when I didn't get on as well. While I hoped she got further help from another passenger and/or on-board staff, I did feel a bit guilty for what looked like a rather rushed abandoning, even though I couldn't follow her round forever. This may not be entirely on topic, but I was reminded of the story by the fact the daily Gloucester-bound train was part of it.
