G'day BW,
There is a swag of material available about this prang at yer Accident Archive mob.
https://www.railwaysarchive.co.uk/ev...hp?eventID=142
It does make for interesting reading.
It has also featured on the 30 seconds from disaster TV series.
Nothing is perfect.
There was a prang involving two suburban trains in Singapore (?) (from memory) that collided at a crossing loop.
That system was semi-autonomous controlled by computers.
Not ever event can be conceived or planned for.
I would much rather have some person perched up the front of a train controlling it rather than some computer.
Steve.
