So, once again, I made myself listen to the "train sounds" on this thread. I turned the volume up, and on a 7.1 surround system you can really hear.
The whistle sound made me throw up in my mouth a little. The chuff of the engine actually sounds pretty darn good. When the engine was far away, I could tell that it is a directional speaker sending out the sounds to the sides. It also had a very rythmic cuff, 2 , 3, 4...chuff, 2, 3, 4. When the engine starts slightly turning the base kicked in and the chuff deep and throaty and was timed pretty well with the drive wheels and sounded more what I am used to hearing on the real steam engines.
When the engine comes to rest, it does not make the sigh, nor does it make the gasping, throaty HUFF HUFF while waiting to go again. I used my own recorded sounds of the DRR to compare.
I could not hear the click clack of the wheels on the rails. The breaking system sounded wrong, though I am sure they use air brakes. At least the bell was real.
As far as steam outlines in China, according to the Encyclopedia of Trains and Locomotives, the QJ weighs 272,160 lbs. and has a boiler pressure of 214 psi, and a tractive effort of 63,340 lbs. To my knowledge the last steam engine operating in China is SY 1772 which operates on the Tiefa Mine Railway. I don't know if she is still running or not. A friend and I were excited about the QJ's when they came to Iowa.
