Easy to say this in retrospect, but there has to be one person responsible for passenger safety 'on the ground', be it a manager, station supervisor or driver. The only one of these people present when the detrainment started, was the driver. To take on this responsibility maybe drivers need to be paid more/trained more, but the buck has to stop somewhere, and it isn't clear to me that the driver believed that traction current was off or on. From the report the problems are obvious, firstly the driver had to communicate with the ARL strategic command at Swiss Cottage and the signaller at Network Rail Route Operations Centre, Three Bridges but it seems that Swiss Cottage and Three Bridges weren't communicating with each other. In addition in order to contact the Govia staff at Peckham Rye station the ROC had to go through the NR Sussex Route Control Centre, also at Three Bridges but on a different floor of the building. Obviously things would be a lot easier if the driver only had to communicate with a single control room that covered an area but with our fragmented railway system where you have various TOCs operating over track managed by Network Rail that isn't an option. Is this what the Three Bridges site was made to solve, or the London Bridge shared office?

Neither tunnel, for different safety reasons. What do you mean by bung, what long term solution are you hinting at?

Yet last time they all had a pilot with them between West Ruislip and Paddington.
One of the problems with this 'divert to Paddington' idea is that Paddington itself simply doesn't have the ability to handle diverted Chiltern services!
It happened about a month ago, the weekend service was half hourly iirc.

Well, I’m not a senior manager, and I work on the supplier side, but I’ve been involved in big projects that have delivered very significant rates of return to the public sector. I am sure some do, but many well publicised projects don't. One might mention various NHS projects, various Home Office projects - especially related to passport control, In the automotive and rail sectors, we are continually bombarded with upgrades and new features that - frankly - we don't need. Yet. They know it's a slow process and needs to be started early to be ready in time, to be there when the demand would overwhelm the previous system.

What do 27 points there have in common? Are there some numbers where you can say - oh that must be a blown fuse?

I also assume *someone* is also paying for all that electrical infrastructure which is now energised but not actually being used to power trains. As if we haven't already been close to the realms of farce with the electrification works we are very close again with the possible rolling stock situation. Is there a cost to the infrastructure being live and unused, a known amount of juice lost to the air with a cost at the rates they pay?

I've seen people reading into the longer installation period for the W&C line as including time to switch over to driverless trains. It seems like avoiding saying that now helps with the unions. We may know more when they announce the bid winner this month.
Fantasy: my post in FPRIAS solves this.

It mentions walkthrough trains. Are there any turns sharper/harsher than on the subsurface line that could make it dangerous to stand on the gangway?

It's not a precursor, it's a requirement. That they can justify the redevelopment while saying they aren't planning to split the line means it is being done just for the crowds with the current services.

Yes. It means they can close and work on one line without requiring a possession on the other line. I hope we'll see it elsewhere.

On the lines with legacy signalling (including SSR), how long would it take to switch over in the event of a catastrophic failure of the current signalling?

Khan's statement felt like a throwaway line to the unions, one he can only say as he won't be making any advances on their jobs like ordering new trains with detachable cabs.
If a computer was doing the drilling it could be measuring its progress every second with ground penetrating radar, but humans could do that too. If the signalling changed but wasn't cryptographically signed off a computer could have rejected the changes, but a human could have noticed the lack of a notice in a staff room/email about changes. Safety infrequently comes down to whether it's human or computer, but how well the signal was made and received by the human signaller, driver or coder.

Thameslink has a lot less dedicated/exclusive track than Crossrail 1, would be interested to know exactly how far outside the core it starts sharing. Crossrail 2 will be on new and largely exclusive track from Wimbledon to Tottenham or Broxbourne depending on Meridan water - Stratford services. The more 'complicated' the southern four branches are the more exclusive track it has.

That would leave Clapton as the only station only on the fast tracks. From the junction not named on Carto north of Hackney Downs to a crossrail built junction just before Tottenham Hale they may have to merge the fast and slow services.

Would that Belsize Park Overground station be the only underground station with regular freight trains passing through? I hope there are some regulations about that.

There's a mention of crossing the Dudding Hill line with a pedestrian bridge but other than that it sticks very much to the proposed buildings (two Overground, one HS2, one Crossrail). The master plan for the site has slipped somewhat and I've lost track of where it ended up.

You can look at the earlier consultations/plans/proposals. This is the cheapest plan that involves both lines served by OOC.

www.britainrunsonrail.co.uk/twitter.com/hashtag/PartnershipRailway?src=hash[twitter url=''] With £38b of public money and £12b of private money, this is a coordinated effort to generate £85b of economic benefits through 178 improved stations and a large amount of resignalling, better track, new lines and electrification. Opinion: Most of this money was already committed. Crossrail and Thameslink are included. I'm struggling to identify any project announced in this. That private money is for new trains which appear to be costed into new franchises, so it's public money/ticket costs. It feels more like a PR campaign to make us less aware of the number of projects ending without others starting up (though counting by number is flawed). [twitter url=''] Good news in that all this is happening but what's newsworthy about it today? Apologies if I've misread this and it is just politics.

You made me curious if any platforms are listed. They are, e.g. Notting Hill Gate District&Circle. Nothing underground at Charing Cross is listed, and those platforms are very young.

www.furrerfrey.ch/en/systems/conductor_rail.htmlGreg Tingey's explanation on LR - '[T]hey simply string a wire parallel & very close to the overhead “rail” for some distance, with the rail slowly rising & the wire descending, so that there is a seamless transition from the p.o.v. of the moving pantograph.'
