The acceleration on the T5 transit is quite impressive.

I've missed that one but then I usually access T5 by road from the west.

The transit is airside, so it doesn't matter which way you approached
the terminal.

Unless you approached it from above.

How would that affect whether or not you encountered the shuttle?

How will the pod cars at Heathrow fit in with this?

Driverless trains have been running on the Gatwick monorail for years.

It's not a monorail,

Agreed, but it's now so widely known as a monorail (presumably because
it has only one rail, as such) that the name has stuck, even though it
is technically incorrect.

and there are PEDs;

As there are on the Heathrow PRT system.

but apart from that...

.... they are both driverless passenger movers.

It's similar to a guided bus. The two concrete rails are quite narrow,
though, and I've always felt a bit uneasy as it runs along without any
obvious means to stop it diving of.

We were looking for ones without PEDs.

It's done in Vienna.

Please explain.

there's some sort of points mechanism to get the vehicles on and off the

I good while back I was able to visit the bits you can't normally see
- ''the shed'' in spotters terms.

Theres no ''points'' that I recall nor anything analogous to them.
The only way to move cars on and off tracks is outside on the
''running line'' and a heavy lift road crane would have to be used.
There is no other means - and really there is no need to.

On the grounds that with PEDs they aren't that different from lifts and no
safety authorities claim they need attendants these days.

In this sub-thread we are looking for examples dealing with "British
rail safety regulator insisting that their be an authorised
(appropriately trained) member of staff on any passenger carrying train."

PRT may not be/probably isn't a train, I guess.

I have just read back catching up on this thread. It seems many are
labouring under the impression you need PEDs for unmanned ATO trains
(in UK).

Where is this notion coming from ?

As a control systems engineer working with ATO / ATP / ATS, I
am neither aware of such a legal requirement nor do I see why it
would be necessary.


AIUI the reason Gatwick and other airport shuttles have PEDs is to
assist with controlling passengers - tipping out several 747s et el
into a terminal can be extremely peaky with baggage and trollies
eveywhere, and passengers who are generally paying nowhere near as
much attention as the average tube punter. In these locations the
higher risk of a passenger/platform incident is mitigated by PEDs;
this higher risk is not there on metro railways. The highest risk is
from stray baggage trollies. They may not do any physical damage but
incidents would be seriously disruptive.

Digressing, PEDs on the Jubilee were not put there for safety - they
are there because the JLE has a tunnel ventilation system. I am of the
understanding that TV is - if not a requirement of new underground
lines - the only means to meet certain other conditions such as
smoke evacuation and/or environmental conditions. Crossrail is having
PEDs for that reason - not platform edge safety (even if the media
people have dressed it up otherwise). I am certainly of the
understanding that Paris stations with PEDs are also for TV
relief, not platform/train safety.
