One possible reason for this is that the ceiling is so low that overhead signage (and thus signage visible at a distance) is smaller and much less prominent than typical. People see a staircase and, not seeing signs telling them they can't, they naturally use them to exit (plus there will the usual proportion of people who ignore one way systems). I'm not sure there is an easy fix for this.

They will almost certainly know the energy consumption of the train in the climate and environments it has been tested in (mainly outdoors in southern Germany I think), but I'm not sure how well that corresponds to tunnels in London. Air con (and probably cooling) will be more efficient on test than in service because the air wont be being exchanged with the surroundings every 2-3 minutes and they aren't carrying several hundred human radiators.

You have the correct line, but not the correct station.

This is despite no reason yet given for the significant/sudden increase in flashed over motors. Last I was aware, the root cause wasn't known or at least wasn't known with certainty. This blog post from 2008 (of unknown reliability) suggests brushes wearing out as one possible cause, although my gut feeling is that if it were that simple then there would be a lot more certainly about how to fix the issue and how long disruption will last.

The impression I got regarding buses would be that normal bus routes would be enhanced rather than a special route or routes being provided.

I too find a handrail running fast to be more common than one running slow. Getting the two synchronised is (as I understand it) one of the most complex parts of escalator design.

Stanmore Junction is indeed just north of Wembley Park, it is the place where the northbound Met and Jubilee lines diverge. For those interested, there is a very old thread about the junction and its name.

Cabs are also a major use of space, with (per cab) 0-2 staff members and equipment taking the same area as circa 4 seated passengers. Coupling and uncoupling units is costly in terms of time, capacity and money so, especially on metro services it is cheaper to run a train at a fixed length all day than to add or remove cars to account for expected capacity, so the cost-benefit calculation for cabs is usually negative. I suspect this is even more so post-pandemic given the relative flattening of peaks. In the days of steam locos, labour was cheaper, you had to shunt locos anyway and there was a much greater difference between the type of maintenance required by locos and carriages, so the equation was very different.

"Inflexible, fixed rakes" is regarded as an advantage in this case. The inter-unit gaps waste space that could be used for passengers and the couplers are wearing out from coupling and uncoupling. The DLR needs more capacity, the only reason they don't run all the current services as three-car trains is they haven't got enough rolling stock to do so at the desired frequency. Previously passenger circulating capacity at Bank was a limiting factor on running more trains there, but this has now been resolved.
Regarding non-articulated stock. Remember that the DLR has some very tight curves and steep gradients. Articulation points are inherently less flexible than couplers between cars, so this may have been a factor.

Welcome to 2024 and with the new year the quiz returns after an extended December break. We start the year with a single part question with a bonus also up for grabs. (click for a larger version) Bonus question: Why was this location chosen for today? If that's not enough for you, then all the unsolved past quizzes are still open should you wish to take another look.

As far as I can tell, Unite have not made any statement about industrial action in London nor about whether they will or will not accept the pay deal.

The [double blocking] method is used everyday for the Tyne and Wear Metro running to Sunderland over the mainline, but certainly wouldn't work for the approach to Euston given how busy the line is. I believe that avoiding the need for this extra spacing, and the capacity constraints it entails, are the principal reason why the new Tyne and Wear Metro stock is essentially a mainline unit rather than a tram-derived vehicle as the original stock is.

The Victoria line has already shown how trains with different automated signalling systems can use the same tracks. I'm sure that Tom can comment with more authority, but I believe that while old and new Victoria line stocks were running at the same time, both were communicating with the same signalling system - something that required a lot of work to implement as a temporary situation and would have required a lot more if it was going to be a permanent operation.

±0.5m and ±0.7m are what I've seen quoted elsewhere.
