So, I just got my Bachmann QJ (2) and I'd like to know ifI have the history right and also would like to have some questions answered since the internet hasn't been to handy. From what I've gathered, Russia ordered then copied a American 2-10-2. Then during their conversion to diesel sold some of their 2-10-2's to China who in turn copied it and made thousands(?). A forum also stated that the QJ's are prone to bering wear, excessive oil usage, rough ride at speed, and poor balancing. I'm wondering why the Chinese would keep building a design that the US abandoned long ago, and why didn't they seek out a more efficient design? By 1960 steam was pretty much dead in the US and it's not like Europe and American steam designs are top secret considering most got scrapped with a few left in parks for all to see. Considering the resources China put into the QJ class, wouldn't have been better to at least attempt to make a Texas, Yellowstone, Challenger, Big Boy, or Allegheny? Okay, maybe not articulated steam, but isn't the Texas the natural progression of the 10 driver arrangement? At any rate, I do believe the US has 3 QJ's now and the last QJ to pull a revenue train was something like this year or last year at the latest (Mongolia).
