Interestingly my coal fired steam roller meets the ULEZ emission standards. Doesn't produce any NOx then? Interestingly, some quite old two-stroke motorcycles have been managed to pass.

How do they work - presumably on axle load?
We had them on the Great Northern trains, but I don't recall seeing them recently.

Was covered by Jago recently
Fascinating story. I wonder what he did in tunnelling that kept him engaged on it when he had lost his leg? (And as various have commented on the video, this is why health and safety comes down on pranks).

Northern line not running in the open sections, vic severe delays due to a track fault caused by ice.
Unexpected snow causing problems?

Wouldn't increasing speed decrease capacity, in the core section at least.
I can't see noise getting to be at central line levels, a better comparator would be main line railway tunnels, given the size of the tunnels and the type of rolling stock

I think its to reduce the likelihood of delays in one part of London affecting services at the other end of the line. That said, some through trains to Heathrow might be run. Stage 5c will see Shenfield trains running beyond Paddington. Next year. After the mess that was the Thameslink opening (and Heathrow T5), I imagine "big bang" openings have been binned and replaced with incremental work-ups. Until you run trains out onto the "other" network you don't have that risk. Once you connect you have the risk of something affecting Reading hitting crossrail and rippling accross to Shenfield.

Where does that put them in the league of stations I wonder?
They can't be helped by two of the larger projects there being heavily-delayed and selling poorly.

On Thursday last week, I caught a Sevenoaks train from Barnet to get off at Farringdon to catch the LizLine one stop to Moorgate/Liverpool St. It's astonishing how many voids they.have managed to carve out for crossrail under London isn't it?
Made me think how many recent(ish) lines and service patterns that required.
The completely bonkers bit is that I could have stayed on to City Thameslink and walked to work.

Out of interest, how did you walk underground between moorgate and liv.st before the new works. Was there a staff route between them?

Glad to hear about the flooding.
It is the dive-under the morden line that causes the downhill, now I look at the map

Oh no! It was fine this morning. A bit empty, but early doors I guess...
Does the new line dive under the loop, it seemed to drop quickly. Also, at Battersea, I noticed a lot of spare crossings by the side of the crossovers. Seems a bit early to be replacing rail, are they just spares being stored in place?.
I like the decor, feels part of the LU current style, following on from eg Westminster station JLE. And a nice nod to Holden in the screens above nine elms entrance.
Just a shame it takes longer than my usual route to the same place via NR and vic.

The problem with centre rail is that the shoe has to cross rails at points. Wouldn't you need ramps etc at every turnout to keep the shoes from clouting everything?

Will there be direct trains from High Barnet branch to Battersea?
If they are direct and predictable, this becomes a possible commute for me, rather than taking the train and changing.

If the American model takes off, they don't need an infinite number of them, they hire out on a short/medium term to prove viability of a given route.

Good luck to them, an interesting idea.
I do wonder if the D-stock can become a universal spot-hire/infil train to plug gaps in procurement, allow new routes to be tested without huge investment etc.
Maybe as well as the swap-out propulsion systems, they need to work on virtual gauging etc so they can drop in more easily

Apart from the suburban passenger traffic from Mill Hill etc, what would it have offered? In terms of direct trains, it wouldn't offer any new destinations. The interchange with the mainline would offer some opportunities - but, on current service patterns Broadway doesn't offer a lot - except Luton airport. After all, any central route would be easier to go via the northern downwards.
If the service pattern could be changed, then getting two airport links might be a winner - interesting balance North London is very affluent and likely to go on holiday a lot, but will any of that traffic go by rail (distinguishing from Heathrow-biassed business travel). This would only work if there was a very good interchange though - how far will people pull suitcases before going by car is easier.
If there was the money, an extension to Broadway would seem sensible, possibly with doubling back to Finchley. Although as a Barnettian, I would not want the inevitable drop-off on the service there.

When people say "fit for purpose", then clearly, the first thing is to work out what the purpose is. A map of just the tube is only helpful for people who only want to use the tube. My personal view is that a map scores over directional internet resource (like sat-navs) is that if you fall off the direction, you may not know it, and can't use wider clues/relationships to work it out (like people driving down rivers/railways etc when following sat-nav).
when I used to use a pocket diary my big gripe was the ones that did zone 1 only - the time I wanted to refer to the map was for when I didn't know where I was going, which was usually when venturing beyond zone 1.
Maybe the answer is to divide the map into 4 quarters?
The ideal would be a fully-integrated, zoomable holographic projection that allows all the necessary information meshed into a topographic map...

as a former Godhelmian, the usual mispronunciation is G'dalming (stress on the 2nd syllable).
My favourite was a north American (can't remember if they were US or Canadian) friend of a friend getting horribly lost on the way over and announcing they were at High Wye Combey. This turned out disappointingly to be High Wycombe

I wonder if the current configuration will continue? I'm looking out over the GN suburban, and I do feel rather sorry for the operator shuttling 12/8 indivisible carriages of fresh air around, not much more than a year after the 3-car 313s got retired

the only deep-level tunneled stations remaining to have two tracks in one tunnel are (I believe) the Claphams, and they are island platforms, and narrow ones at that. If you split that platform width in half to put one on each side, it would be dangerous even by Victorian standards.
To build a tunnel big enough to have two tracks + two platforms would be approx double the width of standard tunnels. As they have to be circular in section, that means twice as high, so a vast increase in volume of spoil to be removed (and then build back up again).

I never knew that. Multiple units were single-manned weren't they? (excluding guard) Why were the engines so favoured?

The Bakerloo trains have an easy life. Last I saw they annually ran an average 102,867km each, compared to Central line 153,615km, or about half as far again. It mounts up over the years! the 72 stock has therefore run for ~50 years. 102867/153615 gives 0.6696 (to 4 significant figures), which would suggest that central line stock should take 33.48 years to reach the same mileage. They've done ~30 years, so they are only about 3 years off the same mileage/age point, which isn't bad given the 72 stock was an evolution of previous designs, and with (apparently) a less cost-driven programme.

The 92 stock is quite a special case I believe? Built to a cost much more heavily than most LU stuff, so lots of weaknesses have shown early The control technology was new at the time and replacement parts are not easily obtained as the technology has moved on The automated train system gives them a very hard life They were bought at the time LU ridership started to rise, and they have had much more use than might have been envisaged For the 72 stock, how much can be robbed off the Piccadilly line 73 stock? If there is a big pool of free spares on the horizon that might influence decisions. Actually the 92 stock is built lighter than most rather than heavier. The weight control was to keep to contract and hence minimise the need to enhance the traction supply whist still giving higher performance than the 62TS they replaced. Some stuff from 73TS could be used or cannibalised as components for 72TS. Also there was salvage from the 72Mk1 and 67TS scrapping. And indeed there are suppliers for wearing components of most of the electro mechanical traction switchgear. apologies for the large re-quoting - "heavily" was not meant in mass terms there, but in emphasis terms - As I Understand It, the central line stock was built with cost much more of a priority over quality than previous LU stocks.
