How to Keep Subways and Trains Cool in an Ever Hotter World

omg u can imagine being stuck on the tube during a heatwave that's just unbearable!!! like 40c is hot enough but add all those sweaty ppl in a cramped train car and its a total disaster . i think its genius of the researcher to suggest using underground water as a cooling system - its not just about reducing temps but also about the air quality inside the trains which can be super polluted. and yeah transport for london needs to step up their game on this one! reflective paint is a decent idea though, i mean who thought that one? lol. but seriously, they need to consider the feasibility of it all - its not just about throwing money at the problem. and what about when extreme temps hit again? can we even trust these cooling systems?

omg can u imagine riding the tube in london without melting it's a real thing right now! anyway, this cooling system using underground water sounds like a solid idea i mean, it already worked pretty well in that chalk quarry near reading. but yeah, transport for london is being super cautious about costs and stuff, which is kinda understandable

and idk about the reflective train paint job tho... it's not exactly the same as having air-con like, don't get me wrong, it might be more cost-effective and all that, but what if you're stuck on a train for hours? would u want to feel all hot and sweaty?

anyway, i guess the real challenge is just making sure this cooling system doesn't break down when things get REALLY hot like, how do they keep it from failing? those are some good questions...

Ugh I feel so bad for those London commuters they must be melting in there 40C is crazy hot even for me! So this cooling system using underground aquifers sounds like a total game changer I mean can you imagine walking into the Tube and it's suddenly way more bearable

But yeah, Transport for London seems super cautious about implementing this tech cost is a big concern, but I'm sure they'll figure it out. And painting trains with reflective materials? genius! it might not be as fancy as AC but hey every little bit counts, right?

I do wonder how that cooling system would handle those crazy extreme temperatures though what if it freezes or something? that's like the ultimate commuter nightmare

I just remembered I tried that new iced coffee shop near my place and OMG it's so good!!! ️ They have this flavor combo that's literally perfect for hot days like today. Speaking of which, I saw someone on Twitter saying they took a dip in the Thames River to cool off yesterday... no idea how they managed that! Anyway, back to cooling systems... yeah, those reflective train paints sound like a decent alternative, but what if it's just a band-aid solution? Shouldn't we be investing in something more sustainable long-term? Like, have you guys tried those air-purifying plant things for your home? They're supposed to help with temperature regulation too...

Ugh, can't imagine being stuck on the Tube in that heat . But seriously, this idea about using underground water to cool down the tunnels is pretty cool . I mean, it's like having a built-in AC system already there, no need for new pipes or construction, just tap into the aquifers and voilà!

And yeah, costs are definitely a concern , but think about all the money they'd save not having to maintain these massive air con systems. Plus, reflective train coatings sound like an awesome idea too - less energy usage, more eco-friendly .

But what's crazy is how these cooling solutions are gonna affect maintenance and repairs . If this system fails in extreme temps, what happens? Do they just leave it to fail or invest more money to make it reliable?

I'm not convinced about this cooling system idea ... I mean, it sounds cool and all, but have they actually tested it in a real London Tube scenario or just some experimental lab setup? Like, what about when there's a heatwave and the Tube's already packed to the brim? Wouldn't that just create more of a logistical nightmare?

And reflective train paint? That's not exactly rocket science ... I've seen those fancy-pants trains in Japan that have those super-efficient cooling systems... how come it's only now being suggested as a cost-effective solution for London?

I get what Transport for London is worried about - costs are always a concern ... but can't they just, like, throw some extra cash at the problem or do a feasibility study to figure out the real costs? I'm all for innovative solutions, but we need more than just "might work" claims
