Openness is probably best.
But 'doing some extra jobs' when you are already closed might be better than opening on time, then closing again for them later.

Is the musical accompaniment to hide the fact that it still has the iconic sound of electric traction, which corporate types no doubt find embarrassing and 'dated'?

I'm guessing that it refers to the LMS electrification of the London, Tilbury and Southend line.

I'll go with the Valentine's Day bit, although it could be a red herring. Perhaps the location is linked to Ash Wednesday?

So you can't cut out a defective motor?
In tramway days, if a motor became defective, you simply cut it out using the reversing handle, and continued on one. A lot less power in that case, obviously; but when you have 32 I doubt that cutting one out ewould even be noticed.
Another useful feature 'rationalized-out'?

In North Eastern terms, a train calling at numerous goods yards was a 'pick-up', not a 'trip' working. A 'trip' was a short working between two nearby places, often fitted-in at short notice when required. Such a working was ICI Cyanide Works to BASF via Port Clarence goods, until it was replaced by a pipeline.

Indeed. How many trains per hour in Hartlepool? Yes, well that's rather a sore point. The number of peak-time cancellations on the District Line recently, has often been greater than the number of timetabled trains between Middlesbrough and Newcastle-upon-Tyne, via the Durham coast. It tends to make the Minister for Levelling-Up sound as credible as his counterpart in Silly Walks.

Once again I'm forgetting that conditions in London do not necessarily correspond with those in, for instance. Hartlepool; where a four-way underpass was replaced by a level crossing in order to save maintenance costs.

That looks like the answer.
I couldn't grasp the idea of something running FASTER due to slip or wear, and the idea of the STEPS being belt-driven seemed quite alarming!

What would it cost to substitute a remote-operated level crossing?

A minor discrepancy between steps and handrail wouldn't seem like a major problem in operation. I'm just curious to know what allows it to happen.

With the locomotive, the variation is at the wheel/rail interface. I wonder where it is on the escalator?

To clarify: I was referring to a friction drive element in the system.
Think of a locomotive; steel wheels running on smooth rail. Slip can occur; wheel diameter decreases with wear. Both alter the distance travelled per revolution of the wheels.
Compare this with a rack locomotive. One turn of the wheels always produces a fixed amount of travel.
There is clearly a friction-drive element in the motion which connects the escalator hand-rail and the steps together. If the hand-rail can run faster than the steps, then it obviously isn't between the hand-rail itself and the device which drives it.
I'm curious to know how the phenomenon occurs.

It suggests that there is a friction element in the drive between the steps and the handrail. Is there a reason for such an arrangement? A safety measure, perhaps.

The FOI answer is couched in today's usual weasel-speak.
Translation is "Ambient temperatures would have gone down, because of the new, more energy-efficient trains. So the air conditioning will just put them back up to where they were before...".
All very scientific.

Post by brigham on Jan 17, 2024 8:43:50 GMT
What would be the outcome of a successful application of air-conditioning on a tube line?
If the cooling apparatus is on the train, might it not create an artificially-high ambient temperature in the platforms and passages, and a sudden chill on boarding?
Perhaps it would be better to use fixed cooling plant, and treat the air on the platforms?

It looks as though the biggest problem with articulated stock, ie fixed rakes, is no longer an issue.
We should be able to look forward to some reduced-weight, highly-flexible trains for the DLR in future, once the message gets out.
|

Post by brigham on Jan 11, 2024 8:31:40 GMT
It IS that simple. An articulated fixed-rake of five has SIX bogies, the new five-car trains have TEN.
The weight penalty is clear, even without the addition of extra cooling kit.
By some financial sleight-of-hand, heavier trains were somehow cheaper!
|
|

Post by brigham on Jan 10, 2024 8:58:15 GMT
The downside of articulation is inflexible fixed rakes. The downside of two-bogie cars is added cost and weight.
The new stock combines the two!
