Mongolian traders selling from train

At every stop along the route of the Trans-Mongolian Express traders are busy selling all kind of goods.

Here some Mongolian traders are selling clothes from the open doors of the train somewhere in Siberia. The goods being sold (or bought) vary from city to city. Many passengers buy food along the way. Apparently they find the “restaurant” in the train too expensive and/or they don’t like the food on the menu.
