I love this. I read so much criticism here, but noise pollution is a main issue when it comes to railroads in residential zones. Yes, punctuality is an issue with Deutsche Bahn. No, this doesn’t fix that instantly. But as an organisation you can work on two things at the same time. This invention is spectacular. I wish more people would work on noise pollution. It makes a huge difference.

> I wish more people would work on noise pollution Absolutely agree. It's one of the most insidious kinds of pollution that has big effects on mental and cardio-vascular health, and is accumulative. Everything from aircraft, to emergency vehicle sirens, to construction and poor housing, is slowly killing people. In Europe we've actually made big leaps forward with regulation, building standards for isolation, and aba…

Contrast with John von Neumann, who "could not work without some noise or at least the possibility of noise. Some of his best work was done in crowded railroad stations and airports, trains, planes, ships, hotel lobbies, lively cocktail parties or even among a bunch of shrieking very minor minors whooping it up."

They will. We're talking of poeple that have no problem stopping a train in a busy station to completely paint it from one side to the other. They'll spray the dog, put a couple stickers on it, and run away.

I'm confused - how do the vandals stop the train?

Like this:

TL;DW: Basically, the conductor alerts the police and stops the train, once they realize that the train is being decorated. If they started moving forward, it could seriously endanger the graffiti sprayers. So that's really the best course of action here.

Rolling stock lives for many decades and replacing it early is cost prohibitive. So I don’t think changing something about the trains is the best option for reducing noise.

Building noise barriers everywhere is probably expensive as well.

You only have to build them were tracks are close to homes.

What evidence other than your anecdotal evidence that a lightweight passenger train creates less noises then a heavy load freight? I am sure there are some differences in regards to design and age but wouldn't you imagine the majority of the difference is in weight? Passenger trains weigh nothing.

"Passenger trains weigh nothing." A bit more than that. And old freight trains are loud, even when empty. Another example, there is a small local passenger train with a combustion engine. Very loud, whether slow or fast. Unlike the mentioned modern electric one from Alstom, who are so silent, that they are dangerous when they pass by a train station and you are too close to the track. You only notice them moments bef…

Sorry I don't do youtube anecdotes.

I think you missed my point, my fault. Passenger trains and individual train cars do indeed weigh considerably less than fully loaded freight. So yes....its not nothing but they are easily double the weight. Leading to my point that when you are 2.5x+ the weight, its a different engineering problem along with an issue of economics.

Freight cars are not loud only because of age but also because of weight and the challenges on both engineering and cost to remedy it. It is hard to compare a passenger train with a freight train, entirely different beasts.

Many things are covered in graffiti in Western Europe. It always baffles me that people are in such a defeated state of mind that graffiti is just simply accepted and seemingly nothing is done about it.

I mean, one way to look at it is just that graffiti is just... fine, really. It's not generally a huge deal in the scheme of things.

Yet up-post said "miles" from homes. That means a lot more tha just close to houses. It means miles from towns.

I live outside the city, so I know the difference in sound at high speed when they pass by. It makes a great difference. Combustion vs electric but also the manufacturing and damping of the wheels etc. Steelwheel on steel can be very silent.

We lived fifty yards from a railroad embankment, just where it bridged a street. It was very loud.

you see, why? ;-)

Think about it this way, if we all owned all public structures, then we all have equal rights to paint it just as much as you have the right to paint your own house. The graffiti artist has the right to paint it, you have the right to hate it. You have the right to paint something they hate, or paint over their stuff. Nobody should be being prosecuted by a higher power for a minor disagreement about artistic taste. U…

No, this is completely wrong. If we own a public structure together, then neither of us has any right to change it except if we both agree to the change. You can't take individual actions on shared goods: you need a process of attaining the consensus of everyone involved (such as voting).

I concur that sounds really good. That's not how it works now though, which is why graffiti artists reclaim the space as the people that use it. Right now, the space is decided by people in power and with money. Rarely do we ever get real say about how it looks, and we never will. If we did own the public spaces and could make these decisions together, then I'd be down for that, and graffiti probably wouldn't be the same sort of subculture that it is.

At some point someone made me realise that almost anything that can be said about graffiti can also be said about outdoor advertising.
