Can the driver deny access to the J door at the other end? Because from the video it looks like the cables and wiring on this system are local and confined to the door it’s mounted on.

I am not sure, but that is not the issue they are trying to design around. Currently if someone entered the rear cab while the front cab is 'on', you would get a warning in that cab. |

It's not clear whether the driver needs to reset the alarm system after every time they use the J door? If yes, then I can easily see some forgetting (especially in the early days after a very tight change of ends or after a dealing with an issue in the saloon. If no, is there a timeout mechanism of some sort? Is it linked to the controls in any way (e.g. automatically locks if the train takes power)? If there is a timeout will disabling this (using the off switch, I guess) be (need to be?) used in the event of an evacuation through the cab done in batches?

If you look, the key is linked directly to the handle of the door I think. As such, the alarm system is untouched |

The first segment of the video shows what happens when you use a key: it unlocks the flap (and illuminates the button to show this) so you can use open the door using the handle. The only (apparent) difference to how a passenger would gain access is the method of releasing the flap.

And also the Key to open up the flap as currently its a J Key which will apart from other areas which will not get disclosed becomes obsolete to open a J Door |

The Waterloo & City ‘92 Stock will have a time-out of “238 seconds”.
Each future Stock conversion will be decided and agreed on an individual basis

238 seems like a strange figure!

238 seems like a strange figure! I wonder if that is the maximum time (plus a little) that you could potentially be driving between stations under green/clear signal, such that you don't have to stop the train to deny access. |

Waterloo-Bank platform 7 = 4.25 minutes 4.25 minutes = 255 seconds, so the journey time is 17 seconds longer than the timeout. That sounds a little long for a rounding difference, but it's not impossible that it's the maximum time no part of the train (or just the leading cab?) will be adjacent to a platform? |

That sounds a little long for a rounding difference, but it's not impossible that it's the maximum time no part of the train (or just the leading cab?) will be adjacent to a platform? Could be 4 minutes 25 seconds = 265 seconds. May be trivial, but cuts it down to 7 seconds. |
