All passenger had DFH3. There might be no steam on this line anymore. In Zhengjiatun station JS 5949 was shunting, also QJ 6571 was seen under steam. QJ 3109 was dead, QJ 2976 and 3182 for scrap. This line to the south is quite steamy and runs through nice and photogenic semi-desert, but poles mostly on the eastern side are a big problem in the morning.
Traffic is high.
There is a frequent busservice the whole day on the parallel running street. The above described section is typical for the whole line. You do not have to visit the whole line I believe. Zhangwu has a depot, where a lot of QJ could be noted. Locomotives are 2-axled diesellocos.
