Victoria line is at 34tph at peak. I think the jubilee line is running at 30tph right now and will be going up to 34tph when they have more trains. All lines will go to CBTC soon. Not having a driver doesn't add any capacity. Indeed it can lower it quickly in the event of something going wrong (may take a while to get staff to the train to fix it)
tph? Thousands/trains/teas per hour?
>Walking anywhere in London or navigating the subway during rush hour means having to make a mad, dodging, aggressive dance against an oncoming tide of people, many of whom seem oblivious to Britain’s long tradition of walking on the left. I feel obliged to point out that this 'long tradition' only exists on escalators in the London Underground. Anywhere else in the country (or London for that matter) we walk on whic…
It took a while for me to figure this out, but there's actually an unmentioned rule in the US that you walk to the right when you're passing people, at least when it's congested enough that you have to choose. I see a lot of people from overseas struggling with this where I work, at least early on.
When coming to London, this always makes me spend extra CPU cycles to ensure that I'm not doing anything wrong.

This has been discussed here before: standing people pack tighter than walking people, therefore all standing ends up with more throughput, at the expense of lower individual latency (for the would-be walkers). But you only need that optimization when escalators are at full utilization. In many cities, escalator discipline is low enough that the walk/stand lane pattern deteriorates when the escalator approaches maxim…
> standing people pack tighter than walking people, therefore all standing ends up with more throughput, at the expense of lower individual latency (for the would-be walkers) If the would-be walkers derive much greater than average utility from a quick journey, isn't it likely that the all-standing regimen achieves higher average throughput at the expense of lower average utility?
