Thanks for that post, welshman!
Even as a mere passenger, I'm rather interested in what happens up in the cab, and how it could affect my journey - so I read that report.
It does seem rather unsatisfactory that the notification to the driver of an Emergency Speed Restriction effectively relied on him jotting it down on a piece of paper, and remembering it when he approached that particular length of track?
As you say: thankfully, there were no casualties - but the result of that incident could have been so different.
(Like the report, I don't attach any particular blame to the driver, by the way: I just think the 'system' let him down).
