These are Eduardo Paolozzi’s ghosts taking their revenge for the destruction of the beautiful mosaic at old Tottenham Court Road Station, obviously. Seriously, though the Lizzie Line is an example of really grand design but poorly executed. Here are some of my observations: a. The quality of material is poor and hinders easy maintenance. b.

Imagine that, in the past, the tube was steam engine powered. If there are peoples who can handle heat deep there, they're the English. But, yeah, it's stupidity.

Back then, the ground itself was cold and acted as a heat sink. People complained of the cold in the underground. A century+ of trains and passengers has warmed the clay, so the stations heat up.

That order (alphabetical) seems correct or at least reasonable to me? Why would I care about the Shenfield train if I'm going to Abbey Wood?

(Yes I know some journeys it may not matter as two trains share a route for a while -- I'm about to board such a train in Boston -- but a sign with two lines isn't hard to scan -- and even with many lines, if the times are right-justified, it's easy to spot the shortest times.)

> is idea that modern engineers are idiots and can't think of anything people 100 years That is not what I was trying to say. I'm saying that politicians and managers are unable to think of things that people 100 years didn't think of. While that isn't 100% true, it is very close. Though most of the time engineers today couldn't think of anything they didn't think of 100 years ago. However sometimes advances in other…

Crossrail uses advanced signaling making very good use of the resource. They use platform screen doors for both improve safety and reliability but also fast loading and unloading. Seem to me these are all improvements and were the right approach for Crossrail. They didn't do everything perfectly but the system is pretty damn good and pretty damn successful. Yes, infrastructure has gotten more expensive, and that is p…

I'm not up on all the issues with Crossrail, but that trains cost too much in the English speaking world is well known and Crossrail is not exempt. Generally this comes down to stations that are much larger than needed and other things that appear to be justified until you dig deeper and discover they are expensive and the rest of the world does without just fine.

Probably clean up discarded biological matter pretty well. Rats have decent cognitive capabilities. I wonder if trained cleaning rats would displace the naughty variety. https://www.theguardian.com/environment/2022/feb/01/swedish-...

Wild rats aren't naughty. They're just animals trying to make their way in the world the same as the rest of us. But they do make a mess and carry diseases, again maybe the same as the rest of us lol.

Agreed, my use of “naughty” is to acknowledge that rats in a relatively natural state have some characteristics deleterious to close human habitation.

Trains cost to much because like many other countries, Britain buys from their own manufactures. Because of the state of British railroading since privatization most of British rail manufacturing collapsed and only a very small number of manufactures are left.

Station being to large is a question of taste and priorities. Saying that such tradeoffs are not worth it is different then just saying straight up that 'the results are terrible'.
