Presumably TPWS▸ would prevent such an accident, or at least greatly reduce the severity of it.
The accident was believed to have been caused by sudden illness of the driver, who had suffered a similar episode previously.
And whilst I rather liked the old trains, it must be admitted that newer types are more crashworthy.
Certainly TSS would have.
Not sure what the last signal would have been on the approach at the time, but I believe the red lamp on the stop blocks was not treated as a signal so the train could have approached on a clear signal as such the
AWS▸ would not of prevented it either
