Another fascinating blog Richard. And unlike so many of them, where there were obvious risks being taken or safety features omitted, with this one it’s so unlikely as to surely have been unforseeable. Do you think the signalmen were reassured by all the built-in the safety features that nothing like that could have happened, freeing them to run the two trains so close? Or was it the old fear of causing a delay for financial/reputation reasons rearing its head again? Were there any additional safety measures introduced as a result?
