Are you seriously suggesting that 50 years later

That was the date that I could find most quickly when writing that
posting. I am aware of other collisions in the same area much more
recently, but I'd have to dig through a fair amount of paper to find the
details.

the controllers
still wouldn't know that there was a train on the section ahead of
a stuck signal and so to warn the driver behind?

The driver who passed A489 knew there was probably a train ahead of him
(it could have moved off). Nevertheless he failed to control his speed
and killed 12 people as a result.

It is incidents like this that led to the introduction of Speed Control
After Trip. The specific device which you think should be removed.
