Post as many train pictures as possible.
All about urbanism and transportation, including freight transportation.

i recently attended a training where we were informed that a degraded compound from tires breaks the blood-brain barrier in salmon and causes them to die.
But the human blood-brain barrier is more robust, right? 
We have larger body compartments outside the brain to soak up those degraded synthetic rubbers, so human bodies will probably tend to get lower intensity doses spread over a greater surface area of tissue to penetrate!
I was going to mention the fish. I didn't know this about salmon. But I knew that rivers that have bridges have a lot fewer fish around the bridges than they otherwise would/should. There is a type of tire that's better for fish (unsure how much better) but it's more expensive so you can guess how likely it'll become widespread.
Recent argument with a Lemmyverse carbrain:
"I have a small business that moves pallets. How would mass transit move my pallet? Case closed." 
As we all know, freight trains are incapable of carrying pallets, it's never been done before, just too experimental.
NOOOOO ITS NOT A ZYBERTRUKKK 
Communism is when no small vehicles, only trains and buses
Do they just think our solution is to cancel cars and not add to public transit infrastructure? Liberals really think they've reached peak brainpower and that new ideas are impossible.
Not to belittle the actual problem of tire rubber particulates, but the wording of the headline is very consistent with a green nationalist focus on "pollution" and "clean air" that minimizes exactly how many orders of magnitude more dangerous GHG emissions are than anything like this.
Also, even this is total bullshit - "more particle pollution by mass?" So CO2 is not a particle? A typical car emits waaaay more CO2 by mass in a month than the mass of an entire set of tires.
Again, not to minimize the actual cause for concern, but wording like this actively minimizes the climate apocalypse that the developed world has created and is sustaining.

i've always been a bit skeptical of the hyperfocus on CO₂ emissions as a proxy for pollution but
more particle pollution by mass
is suspiciously specific. No i will not click on the article.
CO2 isn’t pollution* fyi.
Edit: I think I misread your comment, but to expand on what I mean, some people use CO2 emissions as a way to slam measures to reduce pollution that is toxic to nature, such as catalytic converters and plastic tax. I think this is possible because people confuse the concepts of "We shouldn't poison nature" and "We should stop climate change", which are both technically issues of pollution.
Yes it's a nitpicked measure, obviously the most environmental damage comes from all the fuel being burned.
Fucking hate those bigass trucks I used to see in Upstate New York. I saw more of them when I went a year ago and those bigass trucks almost always had US flags plastered all over them and a blue-line flag somewhere on the back. You'd get the occasional "don't tread on me" stuff as well.
I hate when I see these assault trucks block off bike lanes, constantly get into near misses due to 0 visibility, and make everyone's lives harder because of their noise, size, and universally aggressive drivers. Worst part is they're never used for actual hauling, everyone who actually does work that needs a truck just gets a cargo van like a sane person.
Almost killed me and my whole family in Dallas
Over here all the big ass trucks have Canadian flags and "Fuck Trudeau" stickers (for the not-good reasons).
It's weird these people cling to hating him for covid protocols that don't exist anymore, and that weren't even under purview of the federal government.
There's four of them for every car too, and each car will go through several sets in it's life. Tires don't just dissolve into thin air, these toxic compounds are literally ground into powder and flushed into our rivers every time it rains.

By "bigger ones" I assume this is strictly in an American point of which yeah I agree, there is nothing green about an electric F-150 or whatever.
But we can make small and lightweight cars, these actually exist elsewhere in China and even some in Europe. Of course the American car culture is irredeemable, burn and destroy it all or don't and let climate change do it for you anyway.
Yeah, and if we replace every non-electric car with a electric car...you realize that producing an electric car is polluting!
Embedded emissions? Who is she??
We all agree that cars themselves are a problem, but let me bang the drum a little on remote work because holy crap is that an easy way to greatly reduce car trips.
I happened to take a hybrid job (3 days remote/2 days in office) not long after losing a car to a deer, and let me tell you, despite living in exactly the kind of rural area that cars will always be a requirement to live in, having a hybrid job allowed my family to switch to being a single car family. It took a whole friggin car off the road!
If one can incentivize hybrid and remote work for all jobs that can be performed hybrid/remotely at a national level (take your pick on the nation too!) that would be a very low cost (if not increasing revenue for governments through fines and/or savings) way to greatly reduce how many car trips/miles are driven by car everywhere! That's great for the environment, that's great for traffic, that's great for road maintenance, that's great for workers, and its great for businesses!
Are those particles greenhouse gasses?
I'm steel on steel baby
Independent of tires, lithium extraction is an environmental nightmare of its own, AFAIK, and if I'm remembering right, all of the fossil fuels used in producing a car make up a full half of the amount of CO2 it's responsible for across its lifetime. Electric cars are PART of a solution, and a small one at that.
