Would it still be funny if it was a swastika? Or the n-word? Is that also a part of your glorious fight against evil capitalists? If not, why is it any less legitimate? Clearly the “community” must want it there if it was left up.
If it was a swastika or the n-word I would be very concerned about the nature of the community in that neighbourhood and if I'm in danger. But in terms of how i'd deal with kids seeing it, I'd take it as a teachable moment. I don't have to hide my kids from everything I don't believe in (besides they probably see crazy shit online anyway), I just need to teach them how to deal with it. Anyway, theres a wall near wher…
A “teachable moment” like this is not how childless people imagine it to be, with the parent didactically educating the child with words of wisdom. Instead, the kid absorbs what they see or hear and it appears later on in their drawings or what they say on the playground. Children understand the power of transgression and all ideas are eligible for them to play with.

#393My hart jumped when I initially thought that they had implemented an idea that I had once. Turns out MetaWindow is not an augmented reality display in the train's window, where one can read information on the scenery that one passes through while traveling. What is that city in the distance? When was that church built? How many cows are in that meadow? Stuff one has to know.
I get the idea but I’m glad I can look through windows without being distracted by animated digital information

#394Ask the typical DB customer if they want their trains to be on time or more silent and I promise you, the answer will not be surprising.
Both problems are unrelated

"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…
"It is hard to compare a passenger train with a freight train, entirely different beasts."
Hm, for me they are quite simimlar. Just one was build to be more silent mainly for passenger comfort (it is inded nicer in the modern silent ones) and the other for most weight. But you could optimize freight trains for silence as well. All the loud metal scratching noises for example are avoidable, even with more weight. The ones I am talking about were just not build with noise in mind.

#396Now could Deutsche Bahn please also invest in some actual infrastructure, trains and make them go on time? That‘d be great! Thanks.
Deutsche Bahn pays for the usage of the infrastructure just like any other company using it (e.g. Flix or any of the regional carriers). The infrastructure is the responsibility of DV InfraGO (formerly DB Netz).
What are you talking about? DB Infrago is a subsidiary of DB and is as such governed by the board. The fact that they are separate entities has purely corporate legal reasons.

> Now could Deutsche Bahn please also invest in some actual infrastructure The main "problem" currently is not that they modernise too little, but too much. For the last 5 years or so, during the summer months I need to add one or two hours to nearly all my connections because of construction work that slowly seems to move from cities into the rural regions (I'm not complaining though, no matter what the Bahn does, t…
Yes that’s why track redundancies are important. And not just for construction. Local and Intercity connections would benefit as well.

#398> a transparent noise barrier Most rail noise barriers in Germany are completely covered in graffiti [0], so I wouldn't expect them to remain transparent for more than a few weeks. [0] https://ga.de/imgs/93/8/5/9/3/0/9/1/9/tok_8596521c60eeaa53ee...
DB is also deploying robot dogs against graffiti painters: https://news.ycombinator.com/item?id=40388114
But who do they deploy when the robot dogs get out of hand?
Re: Deutsche Bahn introduces "MetaWindow"
#399How about replacing antiques with modern trains? Repairing tracks? Electrifying all tracks? Those steps would not only reduce noise, but actually make their service usable.

huh. rubber on asphalt is very loud on high speeds, could steel on steel really be quieter? (for downvoters: this is a real question, I'm not trying to suggest it can't be)
Yes, because rubber and asphalt do not really have a smooth surface unlike polished steel. So all the little bumbs give your car grip, but also cause friction, which is noise. One of the reasons, why trains are better suited in theory for long distance transport, than trucks. Little friction, so more energy efficient.
Friction produces heat, not sound...
