Hi from London:

The centre is much more pleasant to walk in, as are most places in the zone.

Pollution is much, much better: if you came to London and travelled on the underground you would have black snot when you blew your nose, this hasn't been the case for a few years now.

I hope NY gets the sake improvements.

London has changed for the better for sure but black snot on the tube hasn't changed at all. I get it from 20 minutes on any deep line like the Victoria. It's from train brake dust, nothing to do with vehicle emissions.

The Tube has a real ventilation issue - not just the brake dust, but also temps and staleness. Some of those lines, it’s like a 24/7 sauna!

I think I read that the warmth from people and braking has baked some of the clay earth around the tunnels, making them even more insulative!

Victoria might be one of the worst for this. You can hear the wheels screaming the abrasion off for long sections of it. It’ll be interesting to see whether the Piccadilly gets better for you when the new trains arrive over the next couple of years.

Because of how old they are there is some really interesting long term data as the earth itself around the tunnels reaches a new thermal equilibrium. In looking for a source, i found a good wikipedia article on tube temp in general.

These comments and the article made me see how much of it is/was due to braking. TIL.

I think the screeching is because the section from Highbury to Blackhorse is one massive right hook that the trains take at an uncompromising speed.

Ha, I happened upon an interesting video earlier today on this topic! https://youtu.be/4MzHt_YLnjw
