Certainly if (as is likely outside the UK) people are disciplined and
refrain from blocking sensors to hold doors open.

Easily solved - make the doors close harder as they do in some other
countries so if you block them it actually hurts. People would soon
refrain from doing it.

The HSE would be wetting their nappies over that if it happened
here. Don't forget on the tube we have to have the farce of a
driver walking down the train checking its empty and closing each
carriage one by one before he takes it out of service.

That's because the car-end doors can be opened by passengers. On Line
14 in Paris, there are full-width gangways between cars, so there's no
risk of a passenger getting on to the track. (And on other lines with
older stock, it needs the Métro equivalent of a J-door key to open the
car-end doors.)

LUL did have a FACT (Fully Automatically Controlled Train) as part of the
design development - it was one of the sets used on the Woodford to Hainault
section, but never went into passenger service (I don't think it was ever
intended to do so). The train did run during the day with the doors opening
and closing automatically with staff ensuring that no passengers actually
got on. The only basic addition to the basic Vic Line system was auto
opening and closing of doors, plus auto start.

OTOH, it was one of the 1960 stock sets.

So how do the passengers get out in an emergency?

Until it breaks a kid's neck...

They already close quite hard enough IMO.

In an unsupervised, computer-controlled situation this would be
downright dangerous.

On the main line, where there is someone supervising door closure, the
doors do usually close quite harshly. Anyone who's tried to hold back
the doors of a Class 153 DMU[1], for example, will know this.

[1] I did this once to assist a guard in boarding, as the external
staff controls had for whatever reason failed. The sensible thing
might have been for me to hold the emergency release instead, but she
operated that and I held the door back once open. The force with
which it then attempted to close was rather surprising.

I think it would be necessary to have side platforms and emergency
release on the side doors like the DLR underground sections do, as
passengers may well try to leave the train while others are still
moving in an emergency, in the absence of any supervision.

OOI, does it have this?

Are the new trains for LUL going to have corridor connections and if
not, why not?

The Picc's 1973 Stock were originally hard & fast in closing and
certainly deterred obstruction. Alas LT (as as) gave in to complains
and reduced the air pressure.

That is a proposal for the Victoria Line I believe but I think you will
need articulation on all cars to achieve this. This removes the
opportunity to swop defective units easily, and operating block trains
increases the number of spares needed. Whether the infracos are
prepared to pay for that we'll see.
