One interesting You Tube channel is Jay Foreman's, on the whole history and geography of London.Very few tube lines go 'south of the river' generally, because over the decades when the majority of the tube network was first built it was discovered that the composition of the ground changes as you head south-east, becoming much more sandy/gravelly and unstable, which prevented the prevailing tunnel-building techniques of the time from being adequate for construction of same.
A lot of urban-sprawl development came later, and then it was found that people were oddly resistant to having their properties compulsorily purchased and knocked down to make way for new train lines etc.
Which is why places like Croydon ended up with modern tram services, years after perfectly serviceable tram lines and trolleybus routes were ripped up.

There is definitely less pollution in the UK now.I wasn’t really sure where to put this. It’s the reverse of the thread really. Are we being lead to believe the environment is more messed up than it is?
As I’ve mentioned before I live within the M25 about 20 miles from London. Now I’m pretty sure 30 years ago you didn’t get to see many stars where we live as I was always blown away with how many you could see when we were at a caravan park by the coast. But for a good few years (maybe more) at least I’ve managed to see loads from my garden.
That’s a good point. We did used to have a large Glaxo Wellcome (as it was) factory.There is a definitely less pollution in the UK now.
All the heavy industry has gone abroad.
My Mum's council decided to turn off the streetlights at night. Useless.'Light pollution' has reduced dramatically in the UK in the past 5 or 6 years too.
This is due to local councils and The Highways Agency moving from 'Sodium' bulbs (the orange ones) to new 'LED' type of bulbs which have almost all of their light directed downwards.
The sodium bulbs used to emit their orange light in a much greater arc, and also (IIRC) at a different, longer, wavelength to standard lightbulbs. They were originally chosen due to their light being better able to cover a larger area and be visible in less clear conditions, such as mist and rain/spray.
These modern LED lights I find are rather hopeless as they do not give off a sufficiently bright light, and also are less powerful anyway. The existing streetlights were originally installed the correct distance apart for the sodium bulbs used at the time, and as such we now have pools of unlit street between the lights.
But, 'short story', less light pollution now.
If it was in Dartford, then my older sister used to work there.That’s a good point. We did used to have a large Glaxo Wellcome (as it was) factory.
Yup that’s us. Lots of people here did. I temped there a couple of times. I can’t remember why but I was sent down to a basement one day and there were these robots trundling around on a lined track. It was like something from old style Doctor Who and a lot more unusual back then.If it was in Dartford, then my older sister used to work there.
I can’t agree with you that newer LED streetlights aren’t as bright as the old orange ones. The new ones were installed in my road a few years ago & give out more light than the old ones. The difference was quite noticeable - it’s like the light given off by a full moon & the white light is preferable to the orange haze from the old ones as far as I’m concerned.'Light pollution' has reduced dramatically in the UK in the past 5 or 6 years too.

Exactly so. The 'brightness' is a function of the light emitted and the angle over which it is spread. Narrow beam LEDs can exceed safe levels (type approvals now look at the brightness of LEDs for this very reason). Essentially two LED's using the same power can have different brightness's, but the brighter will have a narrower viewing angle.'Bright' was probably a poor choice of words TBH....I expect 'intense' is a more apt word.
I like the cartoon but telegraph poles?!
Yes, Mrs T's Mum used to work there.If I recall correctly, my sister worked when it was called Burroughs & Wellcome?
There are still places with overhead power lines that aren't mounted on pylons.I like the cartoon but telegraph poles?!
Fair point. Note to self, be more careful if climbing random poles.There are still places with overhead power lines that aren't mounted on pylons.
As soon as Elon takes something over, the problems begin ...
I can attest to the fact that close to these things are ridiculous, for example the one directly outside my bedroom window.'Bright' was probably a poor choice of words TBH....I expect 'intense' is a more apt word.
I always found the old orange sodium lights were much better at illuminating a larger area, albeit with the sickly orange glow, but the modern LED lights tend to be more restricted in their coverage.
Directly beneath the modern white lights is much brighter, for sure, but away from their immediate focal point the illumination is poor.
Most cars already do. Microcontroller based engine management systems have been almost ubiquitous since the early 1990's.I wouldn’t want my car relying on the whims of an app.
