... Apparently it was due to a suicide between 'Bristol and Swindon' ...
Err ... "person hit by train" ... I've not seen any confirmation whether or not the person passed away. And it's down to an inquest should the person have passed away to establish cause of death, with suicide being just one option that would be considered.
Apologies, but that is what I was told was said to passengers waiting at Swindon (I wasn't there myself), so was just relaying that information on. But your point is well made.
