It could be to give the drivers chance to work alone, as they have no experience of working without an instructor.

I suspect that disruption is a bigger issue than cost, There is probably a strong financial case for doing the work.

"The emergency brake was operated when the train was around 100 metres from the crossing, but even with full emergency brake applied, the train stopped 468 metres beyond the crossing after the collision with the tractor."
Taken from an RAIB report, The train was 2 dmu's coupled, (class 150)

Is "Dead Man's Handle" an official term? I know it is longer but maybe "Incapacitation Protection Device" (IPD) might be more discreet and appropriate. S Stock: Dead mans handle seems to be used, (translated of course) in most European countries

At 60mph an S8 will stop in around 2 train lengths, 16 cars, approx 300 yards.

As soon as possible is not very soon however. train wheels are metal, with no tread, as are the rails so their is not much grip to allow harsh braking

Four Trains currently stable at Watford, the fith will be needed at the north end of the line to start up the morning service.

The ATP on Metropolitan for Chiltern post resignalling is, I understand, intended to retain tripcock/trianstip. Though if it gets to the situation where Tripcocks are only being kept for Chiltern (LU having migrated to a replacement system) then Chiltern / the rolling stock owners might also retro fit the LU system to avoid paying LU to keep the Tripcock system (for which LU would otherwise have scrapped) in good order. I cannot see that happening because of the Chiltern fleet fleet size, and I don't think Chiltern would want to have a dedicated Aylesbury service fleet as that would reduce their operating flexibility. More likely could be the fitting or the network rail protection system, which would reduce Chiltern maintenance and replacement costs, and potentially make it easier to operate other stocks on the route. I also suspect that trainstops are more expensive to maintain than other systems as they have moving parts.

Is there a wrong-road starter at Finchley Road northbound? Because, looking at pictures of Baker Street SCC, there doesn't appear to be one, which would make it seem like the crossover is only available for south-north mainline shunt moves (over which passengers may be carried, but wouldn't particularly want to be, as it would do them no good at all!) It is actually very useful for them as rather than being stuck on a train for an indeterminate period they are able to transfer to the jubilee line.

It is a colour light signalled crossover and is available for passenger use, it is occasionally used when there is a shutdown at Baker street, and trains have reversed there in service on occasions. It is also used on sleet timetables to avoid the need to run de-icing trains to Baker Street. Useful both to save time/mileage, and if works are taking place down the line.

I am surprised that there is no work being carried out on Sunday nights, I would have thought an earlier close, therefore a longer nights work, would have been possible.

At long last these are being installed at Rickmansworth, to be followed by all stations north.
I wonder how long before commissioning.

also with tube stock being closer to the ground there is less room for suspension which would absorb some of the noise.

If a draw up signal can only show a red or yellow aspect the signal ahead is almost certainly approach controlled and will never be green when the train passes the draw up, negating the need for a green aspect.

It would be interesting to know how many journeys are currently made between Watford and points between Rickmansworth and Aylesbury, I suspect quite a few, and would certainly be much highte but for the location of Watford Met and the 13 mins connection at Moor Park, (two changes if going north of Amersham).

Also class 172 is not authorised to run on the Metropolitan line on its own or leading in a longer formation with 165/168s as class 172s are not fitted with tripcocks. When (if) the SSR is resignalled that restriction will probably no longer be required. If tripcocks are not required some other form of protection will have to be installed as Chiltern trains will still be manually driven with colour light signals.

Neasden N/B cannot be used as there is no route available for passengers to leave the platform.

I cannot see it happening in less than six months, drivers have not yet been employed and there is a 16 week training period for them, and I don't imagine it will be possible to train them all without some staggering of courses.

Many main line stocks are not normally turned, nearly all long distance London services have the first class located at the London end.
All underground lines with the exception of the Vic, Bakerloo and the W&C (as far as I know) have a train turning option somewhere. Met on the north curve at Watford, Central in the Fairlop area, District at triangle sidings, Northern at Kennington and the Circle, no explanation necessary.
I imagine that the only place where it would really matter would be on the Circle line.

engineering trains hove to be double ended if working in tunnels as there is no access from end to end if it becomes necessary to change direction, this can occur as an unplanned move, so always.

After being on Borough station and hearing an announcement, "there are severe delays on London Overground", I am inclined to agree that identifiers are needed.

All S Stock trains have to reduce to 20mph to enter each platform and cannot resume normal speed until the rear of the train is clear of the platform. This is different to D Stock and cl.378s which serve the same platforms. Not on the Met. Re read post and now think probably just referring to Kew, Sorry

If diesel units are sitting in sidings ready to go it will be a brave government which tells passengers tough, carry on being shoehorned into class 142's because, EXCUSE, EXCUSE, EXCUSE.
