TPWS-for-trams, anyone?
Doesn't sound like such a bad idea, under the circumstances.

I'm surprised such systems arn't installed already on trams like croydon
that are essentially railways in all but name.

Will these unfortunate deaths be included in the otherwise minimal stats
for "UK Rail Passenger Fatalities"?

Good question.

Yes, the ORR classify them as "non-mainline", covering "heritage
railways, tramways, light rail and metro systems".

These are the first deaths of passengers being carried on a rail vehicle
in Great Britain in an accident since Grayrigg in 2007.

I think the only system where you might be right is Manchester Metrolink
which has both railway signalled and drive-on-sight sections, with different
controller settings for each. Most trams in this country are driven like
buses. The only real difference is separate traffic signals which only apply
to trams (white lights). I can see a case for railway signals on the
off-road sections of Tramlink which would cover the section south of the
crash site to Sandilands tram stop. That might include overspeed protection
like TPWS.

Although buses can go through red lights and crash into trams, killing a
bus passenger:

"Andrzej Karcz, 28, was decapitated after being thrown from the front
window of the bus when bus driver Raouf Mraidi, 29, ran a red light and
slammed into a tram.
[...]
The collision, in September 2008, sent the 468 bus careering down George
Street, smashing into shop fronts before it finally came to a halt when
it crashed into a parked BMW."

The bus driver did a runner, but was extradited back to Britain:

But is in the process of converting to drive-on-sight throughout - may
even be complete by now.

Interestingly, what we see as "tram signals" apply to buses in most
European countries too.

And the last time as many as 7 were killed is even longer ago. :-(

The latest from the BBC is that it was a Wimbledon-bound train that
derailed after taking a 12mph corner too fast. Explains why the driver has
been arrested on suspicion of manslaughter. They are also investigating if
he was asleep. Apparently trams aren't fitted with devices to apply the
brakes if travelling too fast.

but, according to the BBC, they are fitted with devices that apply the
brakes if the driver falls asleep

Ever stranger and stranger

Buses can and do topple if driven too fast round corners. National
Express gave up double-decker operation for years when this happened to
one of theirs.

Yes, fair point. But in general a bus is more likely to skid than topple.
Didn't LT make a point of showing videos of old routemasters that would never
topple over no matter what idiotic moves a bus driver did with them?
Admittedly it was on a skid pan so there were no curbs or other obstacles
for the wheels to get caught on, but even so.

David Icke is usually for entertainment value only , but this is just
hideously disrespectful to the people who died and were hurt. I know the man
is borderline mentally ill, but I can't help thinking he should lose a few
teeth over this one.
