Kanjilearner It means the center (#3) driving wheel does not have a flanged inner edge and is simply flat. This allows longer, rigid-framed locomotives to negotiate curves more easily.
No wonder people in the present don't find modern technology very interesting, It's because in the eary 1900's through the 50's, The world would make everything look extremely complicated and delicate. Look at the crap of cars we have today, all smooth and workable, exterior detail is to much for this time era.
What is the purpose of discharging the hp steam at 0:20 please? Is this is what is termed blowing down the boiler to remove accumulated sludge? Thanks.
Yes, the high pressure jet is used to clear "mud" ( accumulated hard water salts,) from the "mud ring" which is the lower end of the firebox, where all this detritus accumulates...a good blow-out stops this mud accumulating and reducing the efficiency of the boiler.
Blowing out the detritus above the Mud Ring of the Firebox water cavity...impurities in water ( Calcium, etc) accumulate in the lowest levels of the firebox envelope, indeed an occasional " Blow down" to clear this "Mud" outof the Boiler ( accumulation reduces boiler water volume and heat transfer to water)
You exaggerate Chinese labour costs, Lukebccb. I have noticed they have increased, because my manufacturer in Shanghai charges me more this year to produce my company products than other years. But I still find it's far cheaper to have things made there, -as the labour cost is still FAR CHEAPER than in the West. I do take your point though. Another factor will be the Kyoto agreement, so China is trying to reduce it's greenhouse gas emissions.
I've seen them. Pretty cool locomotives. It's also cool to see them operating in their own country like this.
Magnificent!
Hope that they appreciate these locomotives as much as we do.
What are they doing to the locomotives?
Thank you.
摄影极佳！美妙的回忆！Brings back a lot of my childhood 's memories! Thank you.
I never noticed the QJ had a blind center driver until I watched this.
Blind center? Forgive me for asking, but I don't get it.

deloreanman14 Thank you!
Kanjilearner No problem. If you watch the #3 driver closely around 2:05 as the locomotive passes the camera, you can see it's not flanged.
Love this ! The Iowa Interstate RR runs two of these in the midwest!
Wow very good video

If anyone else has heard of or watched 'Thomas: Hero of the Rails', then you should see that this is the same train as 'Hiro'
Actually, Hiro is based on the JNR D51 2-8-2 Mikado steam locomotive, very different from a QJ 2-10-2 steam locomotive.

Yes that would be correct to clean the particles from the boiler!

Anything body, with lines, detail in the frame and wheel structure just looks like it would take 9000 years to build.
都退役10年啦
A 2-10-2? Never seen that wheel configuration before.
В их основе советские паровозы ЛВ.
am I the only one surprised why in China the steam locomotives use horns instead of whistles like in america, UK and etc
中国スゴいです。
私は中国あまり好きじゃないけど兄は中国好きです。
What's with the HUGE jets of blow-off steam?

Aren't they cheaper to run, as labour is cheap and China has masses of coal but not so much oil?

Beautiful loco, shit whistle though.
