China's population is concentrated in one part of the country. That makes it easier to serve them more efficiently with mass transit. This isn't true for the United States. The population resides on the coasts, which you can serve with high-speed rail, but connecting the two coasts with the inland population centers via rail is a much, much bigger project.

Yes, this excuse has been given for the past 50 years. Usually, in reference to Europe. That might explain why they’re building 25,000 miles of high-speed rail in China, but it doesn’t address why the US has zero. You’re being sort of vague with the numbers of course. If you actually look at population densities in Spain, for example, and compare them to California or New York, what do you think we’d find? For some r…

I tried a simple estimate on how much a HSR line would cost from Chicago to Denver. About $20-30 billion. It's a 1000 miles of flat nothing, so it's cheap per mile.

Chicago --> St Louis --> Kansas City --> Denver is about 1000 miles.

Complaining is just something Germans do though. We have a saying: "Not complaining is enough praise."

Complaining is the german way to socialize.

One of my ex-gf's mother is German. She drives her totally crazy with the complaining. And the older she gets the more she has to complain about.

I didn’t know that. But then again, I only moved to Berlin late last year and I came from the UK, which is much much worse.

I still cannot believe how bad British trains are. They seem to ignore that functioning train systems exist, and just do it their own (broken) way.

Yeah I'm trying to get Great Western Rail to honor a delay compensation claim. What an awful company.

I don't make a judgment call towards if one is better than the other but I do firmly believe that 50% + 1 vote is not a mandate. I would really like to see a proper 2/3 majority before you let someone impose their will on the other group. Proportional representation has one interesting side effect it seems. You get more political parties in parliament leaving lunatic fringe groups their own parties and allowing the c…

>You get more political parties in parliament leaving lunatic fringe groups their own parties and allowing the centre mostly to rule. Or you have to put together a coalition to rule which may include cozying up to one or more "lunatic fringe groups" out of all proportion to how many seats they have.

Germany has had coalition governments almost all the time since 1949, and there are very few „lunatic fringe groups“ in parliament. Let alone part of the government.

So i've been following this and feel unsatisfied with the "buzz" about it. Let me explain why:

The best Pictures can be seen here

http://www.xinhuanet.com/english/2019-05/23/c_138082738.htm

whereby the third is the most interesting to me, because it allows comparing whith the existing pictures of the Transrapids "Track-Train-Interface" (for lack of a better term). It looks similar, but not exactly. Would it matter? Who really cares?

What i do care about is how "real" this thing is. Because for all we know this just a mockup on stilts. There is nothing wrong with mockups as such. Except for this mockup on stilts there is no footage to be found which shows this thing on a longer test track, or this thing on a test stand where at least it is levitating in the configuration like shown in the press. Any footage, if existing at all shows different systems. Furthermore neither

https://binged.it/2M6k70R

nor

https://goo.gl/maps/h687Cptq2U4kH2Pm9

show any signs of testing track at the factory, or its surroundings.

So until further notice i consider this as a notion of intent to build, but far from ready. As i said, for all we know, the "production rollout" is that of the modelmaker without the real innards.

Btw.: Anybody remembering

In three years they developed the technology needed, more likely just ripped off the tech from Siemens on the Shanghai line.

I will not bring up any names here. But I know there is a project between CRRC, Siemens and a university in Germany to transfer the knowledge from Siemens to China and update e.g. the controller algorithms Edit: so all the rumors about stealing are not true. The knowledge is handed over

Why so mysterious? https://www.uni-stuttgart.de/en/university/news/showcase/mag...

sigh in case someone mentions the dotted track to the SW

https://osm.org/go/5yfE0BZx--?m=

THAT looked interesting, especially with the stationlike structure at the end. But level crossings like can be seen on gmaps? Doesn't look like separate/different track at all.

Correct me, if i'm wrong.

> What are the other trains doing? Did the next junction switch successfully? These are not things the train driver would react to. There will be a signal protecting the switch, which won't be "green" until the change is successful. If the driver tries to pass a red signal (or exceed the speed limit), the emergency brake is applied automatically. The driver needs to react to unexpected events -- which might mean appl…

I don't think any of these things are reasons to have the driver on the train. The train drivers could be located at a remote location and still be aware of these things. Loss of connectivity already means it's unsafe for the train to continue and must stop, as it cannot be aware of signals or hazards ahead. As far as foreign objects or track failures go, these are not promptly apparent from the cabin anyway. CCTV on…

> CCTV on the track and crossings ahead is better placed for early warning.

That's a lot of CCTV to replace one human.

i can't get no levitation

Mysteriously the end of the branch/spur about a mile to the SW is not visible there. Anyways, doesn't look different to what's visible in gmaps, looks all like conventional tracks.

Naive, irrelevant question. Is kph the correct way to signal "kilometers per hour" in English? I think I have seen this before in videogames maybe. Is it an US-only thing?

"kph" makes no sense - kilos per hour? Offical SI notation is km/h, and IMO that's what should be used.

...or kmph
