Huhhot is not Mongolia's biggest city, but is certainly its most developed and rather pleasant (though the streets are all abnormally wide). What is Mongolia's biggest city, you might be wondering? That honor goes to the coal mining slumopolis of Baotou, served directly from Beijing and Shanghai with many trains a day...the line by JinWuXing under the Chengtie (overhead subway) is actually the Beijing-Baotou mainline going to Beijing North Station. Most trains now skip the last part and head to the huge Beijing West Station, instead.
