Now reported that excess speed was a factor in the derailment.
AIUI▸ , there was a c40mph curve on a c90mph route. The local equivalent of
ATC▸ /
TPWS▸ had been switched out as faulty, without failing the train. There may not have been effective approach control signalling, as would apply in the
UK▸ .
Sometimes I think that
NR» /
DfT» /
GWR▸ etc are wonderful.....
