Congratulation Shenyang for such clean metro system. It has started it some late, but now it is going good, by opening new lines. Currently line 1 & 2 crossing each other.

However, I heard that both metro lines are fully underground, is it true?

What about rolling stock in the metro? Type, manufacturer? More exterior pictures would be nice.

On one pic it seems the train is very wide.

Both Line 1 and Line 2 use B type 6-car trains, produced by CNR Changchun and Dalian factories. Its width is 2.8m, not particularly wide.

Do you mean energy recuperation system?

If not, where can I read about that?

Is it the first engine like that in the world?

no no,this is not a new technology,just a new domain use this motors.these motors are widely used in some Kitchen Appliances,but they are very small,the motors in train are quite powerful and have some different to the small ones,you can find some brief information in wiki
http://en.wikipedia.org/wiki/Electri...agnet_DC_motor
i should point out that this is the first Permanent_magnet_DC_motor train in China,bombardier and Siemens have use them long ago.
you can google Permanent magnet motors and you will find many information.

I don't think the tram was a failure, its still too early to judge. IMO the trams are small and slow probability due to the fact that they are wireless. Which is a bullshit idea in the first place. The trams are running in a new district, I can't believe they would waste so much money just so they can remove 1 wire from the air.

Perhaps the first photo i've seen of Shenyang Metro, from front, because due to fully underground and with platform screen door, it is almost impossible to snap a photo of a metro car on line 1 & 2.

I think this snap was taken in metro depot, am I right?

At last after Tianjin & Shanghai, Shenyang returned its tram system after a long 40 years gap. Better late than never. The new system is really modern..(y)

One confusion, in some photos, I see that they haven't overhead wires, but it carries pantograph and catenary on the same spot, so how then the tram run on that wireless portion? by battery traction?

Are there new lines U/C? It seems metro construction is going anywhere except in Shenyang, where AFAIK there's nothing being built now.

Yes, these trams use supercapacitor batteries.
The charge is done in station (circa 20/30 seconds) and just sufficient to run one or two stations more far.

That would slow things down. A typical stop dwell on a good tram system is 10-20 seconds. Does the 20/30 seconds include pantograph up and down?

This is a foolish idea. When tramcars will run on wire-free area, thay will stop on some stops, then rise the pantograph, than charge for further running, then fall of pantograph, than running again. How foolish.

It was far better to running traditonal tram with continuous power supply from overhead wire. I suggest, new routes should be constructed with overhead wire. Wireless tram is much constly for maintenance...

Could anybody post here some details about former tram system of Shenyang, which was closed in 1960? - with some photos & a map of complete network of that system?
