Yeah, the doors where a problem, a few causes to this where that the dust and small pebles that people bring on the train collect near the edges blocking the doors so that they dont ant to open. The tolerances are very small there in order to make the door as sound and airproof as possible. Another problem is that it are electric engines that power it the door, and that the tolerance on the focre needed to open them automaticly in case somebody gets stuck in between them was to narrow, causing them to refuse to close when again there was to much dirt under it.
Also the grears bringing the power from the engin to the doors are a bit to weak.

all three of these problems have been repaired/improved.

Also, those trains run on a whole network controled with windows 3.11 :)

State of the art siemens electronics huh, sure....




I would not say the old ones are better. They have heating that only knows 1 setting, Sauna. The doors close no matter what, and they hurt like a bitch when you get stuck between them. Also, when they are closed and you push the right spot you can open them with 1 hand. Also no airco in summer.
There is even a model where the doors just slam shut with barely a warning, dangerous and anoying. Have seen people get hit by those since the time between warning and closing was less then the time needed to get out of the doors there way.

And the only thing i have to say about electronics, they are all made by underpaid underage chinese working 80 hours and more a week. It shows in the quality.

Siemens electric = those applications in electric panel like you find in high voltage distribution transformer, fuse boxes, etc.

If we are talking about German trains, hmmm... Krupp Spoorbau perhaps?

Is this Siemens Velaro model that you are talking here? Or just inter-city train/subway model?

For Subway, this is exactly the same problem with Singapore's Hitachi MRT. Chewing gums, bread crumbles, spilling waters will jam the doors and sensors, hence you are not allowed to eat/drink/smoke inside. The whole nation banned chewing gums, because it jammed the doors once and shut down the entire network.

As an IT guy, I have to trade-in between performance and reliability. Sure you can have the beloved Windows XP that attracts tons of virus or the still buggy but supported Windows 7 that put too much toll on the computing resources. Or the practically useless Windows 8. Or you can have Linux, another reliable setting.

For application in industry where safety is number one, reliability should be prioritized, hence the use of older, rugged, proven, and not fanci-fied systems. Even in planes as sophisticated as Boeing 777, the processor they used to calculate fuel is still Intel Pentium 2 grade in terms of speed (in Mhz).

Same goes for F-16's fly-by-wire computer (FLCC, as shown in the MFD), which if you read the references, gives correction input to control surfaces (aileron, elevator, rudder) in thousands times per second. So the plane keeps flying straight and level without pilot's input. It needs to correctly read the input from sensors (pitot tube, g-meter, inertial reference unit consisting of accelerometers and gyroscopes, etc) and then translate it into the correct electric signal to the control surfaces, so it will make appropriate movement to counter the inherent flight instability characteristics.

It doesn't take an Apple iPhone's processor to do this. Yes, it is old fashioned, but it keeps the plane from constantly crashing (albeit some software errors has caused the plane to crash).

So far in the last few weeks, Russian and US Navy ships have been passing by my ferry on my way to work every morning... What the hell is happening in the Black Sea, I've seen more than a dozen foreign ships by now...

My guess: converted to Islam, possibly in prison. Muslim gangs are not unheard of in the san francisco area.

I thought MS-13, the Vatos, homies, are all ardent Catholics because of their Latin American upbringing? What's up with the Santo Muerte?

Now they are joining the Shi'a? That's pretty weird.

^Thta´s what I heard, too. US-Armenians fighting for the Assad regime. Interesting, how the opposition against militant Sunnis can unite the most opposed groups...

Anyway, if you haven´t seen it, yet, I can recommend watching the Vice News Dispatches about the Crimean conflict. Their reporter has a serious pair of balls and gives an interesting insight into the whole situation. Their whole channel is really good, btw, so if you have a lazy Sunday and want to watch some good docus, check them out.
