A lot of the bits on the 72 stock can be constantly repaired as needed, where more modern stuff needs to be replaced new.

It means that the train in the platform is signalled to depart the station, information provided for station staff as the driver receives this in the cab.
On sub surface stock the white lights are on the train with the door indicator lights.

I lived up North but I remember boarding the guards car as a 9 year old travelling from Epping once and thinking "what a primitive system", would never have guessed that I would be doing it 30 years later.

Interesting numbers, the times from Harrow to Moor park don't sound right, 60mph against making four stops on route. additionally you need an extra minute to cross from the local to the fast between Moor Park and Ricky.
Just checked from the info I have, not a timetable
Moor Park Ricky Fast N/B 11.5 mins, local 17.5 mins, this ties in with your info.

Agreed but not always practical at this time of year because of daylight hours.

I would stand leaning out of the train in hot weather, had to remember the Colindale tunnel though.
Both doors open if the car was empty.
I am not aware that it was expressly forbidden though I can imagine there would be issues if a passenger fell out.

Presumably Chiltern cannot crew the shuttles they usually run between Harrow and Marylebone when the MET is closed south of harrow, so a compromise is to run 6 car trains, social distancing will also be relevant to the decision, as said higher up in thread, 6 cars are too long for Ricky.

But would the underground have been built to a bigger gauge, the tube lines were not built to the loading gauge of main line railways and building tubes to Brunel's gauge would have been both expensive and difficult in the 1800's, I suspect that a narrower gauge would have resulted, possibly narrower than we have now.

My thoughts were, when I created this thread were either bottom fed third rail or overhead rail, with on board batteries for stations and other areas where installation may be difficult, however I had not taken into account that new tunnels would have to be bigger, to allow for evacuation and so may as well be overhead wires.
I assume that building oval tunnels is a non starter so there will be spare height available for wires.

Given todays health and safety considerations I cannot imagine 3rd/4th rail being allowed nowadays, what would the alternatives be, considering the lack of tunnel space available.

I visited every LU, LO, DLR and TfL Rail station in 2017 (the latter was just Liverpool Street to Shenfield then), entering or exiting. It took me 8 months, but I could have done it very significantly quicker had that been my aim (out and back in would be quicker than alternating train and walk between adjacent stations that I did a lot of for example). If you literally just have to pass through the gateline in at least one direction, then you are definitely looking at several days at absolute minimum. More than that quickly adds up. In ~2011 I did the London Overground circle (Clapham Junction to Clapham Junction via Shepherd's Bush, Highbury & Islington and Canada Water), taking at least one photograph of at least one entrance at every station en-route. I think that took me about 8 hours. edit: having checked I did the Overground circle in December 2012 and Clapham Junction to Wandsworth Road took 8 hours 10 minutes (a signal failure prevented me from finishing the route) That must have been seriously frustrating.

In addition to the good points quex notes, running an IOWSR train on the Island Line would require a driver from each railway in the can (one with stock knowledge, one with route knowledge) which currently presents health and safety challenges due to Covid-19. and a fireman

Am not sure if Chalfont and Latimer needs to be added to the list, there is a terminator from Chesham on a Sunday evening, Rickmansworth does need to be added however, there are quite a few late night terminators when the service is winding down. Hmm, I can't remember what my criteria was exactly when compiling that list but it doesn't appear to include stations where trains sometimes reverse - e.g. it doesn't include Debden or Dollis Hill which have reversers throughout the day. not nit picking, your list makes interesting reading, however wouldn't that criteria exclude Rayners lane. It does look as if mid line reversing points were not included, Kennington not being there makes that apparent.

I suspect there are quite a few reasons why not, firstly the couplers will be different height, secondly you would have passengers on an unbraked vehicle, (swinger), deff a no no. Thirdly unless the compressor was working there would be no air for the doors., I am sure there are many more issues which could be added to the list
You would have to go back a long time for the option on the Island to run a shunter with ancient coaches.

Am I correct in thinking that the ones on the Uxbridge branch will not be changing because of the pic trains, as most have spare platform length but mirrors monitors in the way, and potential signal sighting issues

Instead of having everything going through the train management system would it have been better to just let that be concerned with the mechanical running of the train and have the passenger information systems away from that, ideally on a drivers tablet.
Big advantages I can see are that it would allow easy changes to information provided to passengers,particularly during engineering works. This could just be downloaded wirelessly to the tablet when the driver booked on without any actions needed by the driver.
It would also be possible for all duties and timetables to be loaded and for it to display how the train is doing for time, relevant on some of the outer sections with infrequent services.
This may also take some obsolescence out of the system as, hopefully, when technology changes it would just be necessary to develop a new app.

This may be the reason for locking out the rear doors, but some would have to be locked out somewhere as the patform is not long enough.
I would not have thought that the distance to the met crossover was any less than from Baker st platform 3 and the circle.

I am fairly sure that LUL would not be allowed to introduce new door cut out areas which were driver operated.
There would be plenty of platform space once mirrors, monitors were removed, transition, while both stocks were operating may cause issues but I doubt it.

The cocks on a train. In less PC times staff, who were not drivers or guards learning the mysteries of the the triple valve, were told the train was not operating normally because "when the cock is up it is in, when it is down it is out". If the the trip cock had been cut out you should expect to see two people in the cab; driver and observer who could be the guard or a station staff member (including a booking clerk who did not have any uniform in those days). Indeed, though that did not really apply to tripcocks as they are normally down, although the trip cock isolating cock, which was normally on the front of the train conforms. These are large and yellow on conventional stock, to be visible from the platform. Totally off topic, but some of the mnemonics we were taught were far worse than that. Deff not suitable for this forum.

two issues which come to mind.
Firstly can you imagine the problems getting Network Rail to agree, and secondly, what are you planning on doing with the drivers outside the peak, or are they going to work 4 hour days?

Was there a similar Incident, minus the Whale, at High Barnet years ago, somewhere around the 1960's glad my memory wasn't playing tricks, well before my time however as I started on the Northern mid 90's however I seem to recall the cause of this one was a driver trying to save time by closing the drivers brake isolating cock, (DBIC) while approaching the stops, in order to save time. Effectively switching off the main braking system before stopping.

Is it just people like me, who live near Shildon, who find this whole thing obscene? Obscene because they come from China, or because there are new wagons being bought.

The signalling a Neasden does seem to be quite reliable, so can't be all bad.
The issue with Chesham is that it is a long walk for someone to check that the track is clear. (Nice views though).

they have had signals remaining at danger on the Chesham branch following Pway work where a trolly has passed over the axle counters one way but not when returning.

The red/white signals do not, as stated, but the entry exit shunt signals do, these are controlled by Baker St. or wherever they are now?

They appear the same, however, the old ones showed 1 white or 2 reds, the new show 2 of either.
