Who would like to see new class of tubes?

[Kevo00]

Oops, sorry, haven't seen any of those either...will report back once I do.

[jvassie]

Was at Amersham for several days 2 weeks ago and no new stock seen. Unless it came out since?

[Chris]

Yes the S-Stock is out and about now (a week ago-ish). BBC London News did a feature on it - Boris was an idiot, and people complained that deep lines don't have air-con, and won't for a long time. It still amuses me that we get London News, despite being a good 30 miles outside London!

Can't you retune the TV or change some setting on Sky?

[Chris]

1) Re-tuning probably won't help, as we are actually meant to get the London news - I guess its because most people who live around here work in London, and anyway I actually prefer it, as it actually has some 'real' news.

2) Ugh that Republican piece of crap that hates the BBC .

[LaSeandre]

As of today, Sone S-stock trains have been built and delivered, behind Class 20's (amazingly, woldnt have thought they had the power...) I think they are only used for testing at the moment, dunno when they would be in service

It's 2 pairs of 20s top and tailed, thus:

20-20-wagon (coupler adaptor)-S stock-wagon-20-20

In other tube news, I expect people have seen this:

Been a while since there was such a runaway train oopsing on the tube, but I remember once in the 1990s a Piccadilly line train with passengers on it ran away past Caledonian Road. This is the sort of disruption that makes me happy that I no longer have to travel on the tube regularly!

Click on the link to the BBC news page, and all will be understood.

You should see the Daily Mail's story for it:

Class 165, it's a spammer.

This is OUTRAGEOUS! Now only did the nationalised socialists allow the train to run through so many stations, but they also allowed it to magically morph into a Victoria Line train and change lines too. You don't get this in THIRD WORLD COUNTRIES so why do we have a THIRD WORLD underground system? Time to ban immigration!

Runaway tube trains cause cancer!

You have to love the daily mail

London Underground staff decided to allow the train to continue...

Errrr I doubt they made that decision Mr Mail, I think the runaway train made that one by itself...

Also, I'm no expert - but if the train, travelling between 0-35mph (according to LU) hits the back of the train actually going to do that much damage?

Given that the worse case scenarios is the passenger train would be stationary, so impact speed of 35mph.

[Kevo00]

Even if it just means some old dear gets a bit of a fright, its always best to avoid impact. And a car travelling at 35mph can still kill a child, for instance.

But I agree, the Daily Snail's tone is the usual anti-rail garbage.

Trains have so much momentum in them that a 35mph collision would be absolutely disastrous and fatal. The Moorgate disaster train was doing 40 when it slammed into the wall and killed 43. The crash at Cannon Street injured 524 and killed 2, whilst colliding at a paltry 10mph. So don't underestimate a train speed and its potential for disaster!

Maybe, but I gave the benefit of the doubt .

And I have to say I would hate to be on the tube during a collision, even if it is only 35mph - its momentum not speed!

Quite right. I love the tabloid style emphasis on the scary bits, though.

Yes and no - reading into those does say a lot, but also suggests that other factors had more to do with the deaths then purely the closing speed.
Train on train would be different, as both would behave dynamically (rather then the static nature of a brick wall or buffers). Which would at least (theoretically) give a lower impulse on the passenger train. - Are they any other similar low speed crashes (tube or national rail)?

Also does anyone actually know the size/weight of the runaway train?

I just never believe the press when they shout that catastrophe and deaths were only just avoided - either that or i am in denial that something that dangerous and perhaps so easily avoided could have happened in the centre of London

This.

[JamieLei]

I'm not too sure whether the confined nature of the tunnels would cause more or less deaths due to the carriages not being able to telescope...

ie: http://en.wikipedia.org/wiki/June_22,_2 ... _collision

[EXTspotter]

Wouldn't the afct it is in an inclosed space mean that telescoping is much more likely than overriding as there just isn't the space to override, even with the massive energy. The whole fact that tunnels are a confined space means any collision is likely to be more damaging than in an open space as the energy carried by the train has to go somewhere, if it cannot fly 50 feet in the air then the energy dissapated in such a movement would be "contained" in a confined space as that type of large movement is less possible.
