Qing Kong 还用保留吗，富拉尔基到处都是

这是很好的观光资源，听说可以动的前进型都被美国人买走了，好像都在Iowa州，他们不但当成载观光客用，还会偶尔拉货。

6546好像已经报废了

American's project to Japan's Railroads & by this reason it'as named Mikado.

Not surprising since this is in the region that use to be called Manchuria, and was occupied by Japan and Russia for some times. But even before the Japanese occupation, this area was the industrial heartland of China. I believe most of the steam locomotives are also built in this area.

Nicholas Kotsidis gasoline covered coal with a hint of firecrackers.

It says in the description that it pulls coal, so probably in a mine, using coal powder and tiny scraps that they cant sell:p

And i looks amazing doing it!

@@oljefri This is the Sandaoling Coal Mine in northwestern China. I understand that they feed these beasts raw, unrefined coal, and they are hardly ever cleaned.

They could burn oil.

The steam is the venting of pistons from the air pumps. Older pumps such as single phase often vented through the smokebox, more modern including high capacity air pumps like the cross compound (2 phase/pistons) have steam venting from each side of the pump, in both up and down pumping. Steam air pumps are set to maintain a constant pressure in the Main Reservoir, usually at around 100PSI, thus the pump is woking almost non stop to maintain that constant pressure. Unlike diesels that have a high and low setting of around 105 PSI and 125/130PSi at high setting. In affect they work at all times with magnet valves operating to start the actual pumping called a loader valve, at the low pressure then stops at the high pressure when the unloader valve closes the pumping.

Colin Hussey, thanks for the cool details, but what I was specifically curious about is what is the engineering rationale for conducting the air-pump exhaust up to that location instead of just venting it close to the air pump(s). In the US Norfolk and Western "J" class, for example, there are cross-compound air compressors, and the exhaust steam from them seems to be vented near the main cylinders, at some of the same vents where the main engine exhaust goes if the cylinder cocks are open. Even that, I don't get the point of, as opposed to (hypothetically) venting right at the air compressors.

The way the U.S steam pumps are vented seem different to other countries, although some years back on a U.S rail fan site a photo was put up of a larger steam loco, that had a wisp of steam behind the funnel, and someone asked regarding what it was, outside of myself only one, maybe 2 others said it was likely the pump exhaust. ON NSW Australia, our steam loco's had either single phase pumps or cross compounds, in the main the single phase pumps had the venting to smokebox except for 2 classes of locomotives that had venting to atmosphere, both of them interestingly sound very similiar to the Chinese JF, (had two single phase pumps working together to provide the capacity) JS, QJ, & SY have cross compound pumps, although the QS are quieter. Our more modern steam had cross compound pumps, in 3 classes had twin venting pipes owing to high capacity of, and all vented to pipes running behind funnel. This has also created a problem for modelers of Australian prototype especially for sound installations, the U.S sound decoder makers were sent sound files that included the steam venting and they tossed them out owing to, in their opininon, the sounds were faulty as they had a lot of noise in them. The colder the climate the greater the steam exhausts in vapour, my first trip to China in 2001 my hotel room was over the yard at Chenge, and I heard the pumps and thought there was a NSWGR 36cl mogul or 30T superheated engine working owing to the pump sounds (the 2 with single phase) not long after I heard the chime steam whistle and it reminded me completely of a NSW 38cl express pacific type. I always thought the U.S must have vented their locos to the under neath of the loco's and I saw a video of a preserved loco that had the pipe and it was quite small venting to the rear under the cylinder. If that happened in China, or here in the colder climates, the driver would be hard presses to see the road ahead owing to the extra amount of steam that would come from the vent pipes along with steam leaks that were very common from the cylinders, bad enough as they were anyway.

I see, there could be a visibility problem if the steam weren't vented somewhere away from the engine driver's line of sight.

In China and NSW the air pump is on the firemans side, opposite to U.S, with the vent pipe on top of smokebox behind funnel either facing up or angled like the Chinese engines it did not impact on vision. Bare in mind the conditions you see in the video is in temps near 0 centigrade

+Han Frank What i was seeing on youtube show me not!

Pedro the Chinese primary main line steam loco the QJ are 2-10-2 not 4-8-2
