Just noticed recently that the RailNation QJ, a Chinese freight loco, is a lightly-reworked copy of the Russian P36. They aren't that all that similar visually, even if you don't count the glaring error that the P36 is a 4-8-4 wheel configuration whereas the QJ is a 2-10-2.
The in-game "QJ" is a 4-8-4. Either it's a very bad model or it's misnamed. I admit I have yet to search for a Chinese version of the P36; it wouldn't surprise me if there was one, there are/were several tanks, for example, made in China which are more or less exact copies of Russian ones. In prior years (maybe less so now) Russia shared designs for machinery and such with China.
