Unfortunately, life is not black and white. Even without knowing anything about graffiti culture, there is a border between defacing and improving. And graffiti artists are moving over that border back and forth. Some of the most beautiful art I have seen are graffiti

Good username for this kind of talk...

Noise reduction with trains is probably best done with improving the trains. I live next to a frequent trainline, so I can say: There are modern long electric passenger trains, that barely make a noise at all. And then there are old freight trains, that can be heard from miles away. Since I doubt this noise barrier will be placed everywhere except at some very special key areas, I rather want the Bahn to focus on bet…
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 before they wooosh by.
And if you want more than my anecdota of everyday experience, there are tons of youtube videos of different trains to see that trains can be loud, if that was not a manufacturing concern, or silent. Usually, the older the louder.

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.

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 wonder how you think this works in practice. Do you think the public structures we have and how they look are not just basically whatever aesthetic taste the people we elect have?
Sometimes councils put up several designs to be voted on by the public, but they will largely follow a bunch of design norms that will be whatever the architecture firms they hired think is trendy, for example.
And how many election programs even talk about artistic taste? That's not why we elect people, and making that an election point would be a distraction from real problems, so why not let society be and if people are more artistic in one area and make more public art, let them make it?

could the old wagons have noise canceling skirts?

Life would be meaningless if it was just black and white. Fortunately there are times that we're reminded that people do live in cities and do stuff other than just minding their own.

Someone should probably tell that to the graffiti "artists" in my town

For intercity trains it doesn't matter what the propulsion method is though, since every train will make a lot of noise at speed. It's improved with aerodynamics and better wheel / tracks, but ultimately noise will be an issue. Consider also cars where at speed the noise is not due to the engine, but to wheel / road noise.
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.

God I hope they graffiti the robot dogs as well because that would be so funny.
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?
Re: Deutsche Bahn introduces "MetaWindow"
#370I 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…
It's all about whip cracking! Who knew that was such a thing. Like the mindless honking horn of the past. Thanks for sharing :)
