As usual, I drew another picture, which is still related to the railway
In the picture, on the left is China's first generation of main line diesel locomotive named DF1 （东风1/东风3）and the right is China's largest and most technologically mature steam locomotive called QJ，（前进型蒸汽机车）<In fact, QJ and DF is Chinese Pinyin, a kind of abbreviation similar to English phonetic symbols,In Chinese, QJ stands for advance, enterprising and progress，Similarly, DF comes from a famous saying once popular in China:“东风压倒西风”Please forgive me for using Chinese, because the time background and deep meaning behind this sentence are too complex for me to translate accurately>These two locomotives used to be the first generation main force of Chinese Railways，DF1 is the product of imitating ТЭ3 diesel locomotive of former Soviet Union，QJ type is made in China，After witnessing the development of China for more than 30 years, they retired in the 1990s and gradually ended their service career，In fact, China once sold 5 QJ to Railroad Development Corporation（I haven't heard of this company at all） for dynamic preservation and sightseeing，In 2006, after arriving in the United States, the locomotives were put into service on the Iowa Interstate Railroad.Fourteen years later, I don't know if these locomotives are still in service in IAIS.
Finally, thanks for watching.because I'm a railway enthusiast, so I like to draw trains in daily life~
