I can't imagine something being 160 kilometres away, but I can visualise 100miles being the distance from here to Birmingham quite easily A matter of habit, I think . I can't really understand if a 6'6" person is tall or if 5 F is cold unless I convert that to 198 cm and -15 C .

Aluminium doesn't corrode, it's a non-ferrous metal. The term " corrosion" is not specific to the ferrous metals . However there will be a 'reaction' chemical or electrical, I can't remember It is called galvanic corrosion. The surface of aluminium forms a tough oxide layer Yes indeed . Aluminium is in fact pretty active metal.

With this in mind, as a District Dave Forum Administrator, I'd like to pass on the condolences and thoughts of the staff and membership of the forum to the Moscow Metro Railway staff, the passengers, their families and Moscow Emergency Services who had to deal with the sad events of today. Thank you... The most probable cause of disaster, as Investigative Committee of Russia stated, is as follows: a newly installed point was not properly fixed, causing train to turn to the right at full speed and crash into the dividing wall.

"Announcements must not be continuous, to avoid irritating passengers. They must not be made when a train is arriving or leaving, as this will interfere with the quality of the broadcast" Quite sensible idea .

If people complain about trains not big enough, think again. Whoops! Don't they have standards for train dimensions?

I tried to tidy up David's links but altering the links to include the whole link doesn't work so it looks like it's a Proboards' issue rather than user error Proboards don't like links with special symbols like @ to be included as is. However, they work when hidden behind the text, like this: This url may (or may not) show the place .

I'm surprised this is published so soon after the court case is over... In fact, it could have been published earlier, but was delayed due to the court case.

The Moscow metro also claims 60 tph It never did . IIRC it is 48 tph using ATP. Door control there is aggressive to put it mildly Because delays accumulate very quickly, especially during peaks. But not a rubber tyre in sight... Train acceleration is limited by standing passengers' comfort at about 1.0-1.2 m/s 2. You don't need rubber tyres to achieve this . The highest timetabled frequency on the Moscow Metro is also 95sec headway (38tph) AFAIK it is 39 tph on the busiest lines during peaks. I have not seen a Moscow WTT - assume that such things are probably still state secrets ;D It is something nobody cares about. More useful stuff like station open times and first train departure times are on the official site already. Problem with high frequency service is dwell time. Moscow went from 42 tph down to 40 tph and later to the 39 tph solely to improve reliability and decrease chances of late running. It is not a technical issue, it is problem with "wise men" holding doors, rubbish getting into them, etc.

Would it be possible to build a new station on an existing deep-level line? Yes indeed, see Tverskaya station in Moscow. It is difficult and expensive, though.

As far as I remember in Russia such toilets are forbidden to be used inside cities ;D Yes indeed. But it is definitely not Russia, rolling stock being the most noticeable clue .

I wonder how Moscow treats SPADs though By sacking the offender. However, multi-aspect signalling and/or ATS makes avoiding SPADs easier. what style of driving is most common? Acceleration from the station - coasting - braking at the next station. You don't really have much choice . The escalators are white knuckle rides in themselves. So fassssssssstttttttttt............... I've never noticed ;D. Why not be specific; give us one example of a procedure we follow on LUL or a piece of legislation we have to work with that you think is unnecessary. 'No passengers into the sidings' rule. In Moscow, it is a passenger's fault, some got fined for that.

the current limitation on speed is to do with the vast deal of legacy signal positions on the Northern The question was about acceleration, not top speed .

However, do you mean the old Park Royal & Twyford Abbey station that closed in 1931? It was my first thought, too. According to the informed source, no traces of it has left to the day.

Thanks Mr. Flyer. Obviously no fare dodgers in those days. Not really much, I think: Anyhow, you won't expect fare dodging from someone who has "reputation of ... a straight, honest man" and buys a ticket even when shaken and in hurry:

xUSSR metros use 3-rail setup with great success. However, conversion cost would be enormous, so I'm afraid it is a non-starter.

And just who would pay for this non-standard batch of 'S' stock? Just out of interest, what is the problem with ordering S4 stock (I must have missed the explanation)? E.g. Moscow metro basically orders not N trains, but X DMs and Y NDMs, so making a 4-car train requires simply a bit of shunting.

They do not need to be stronger than they are. Reason: when a shoe runs into obstruction, you want to limit damage to the shoe itself, avoiding damage to the current rail or shoe suspension.

I understand the rule and I think it is a good one just did not seem the correct way to phrase it It is phrased good enough to be understood, so there is no need to change it.
