The locomotive was new, but the cars… not so new. They were in acceptable condition (legroom ok, and rather comfy seats), but the ageing air conditionning was struggling with the outside furnace. The train manager obliged us to shut all windows and blinds (on the sunny side) to save the energy, but air circulation with openened window would have probably been more refreshing.
So we were wet for three long hours, with the loud and saturated sound of a TV series in russian.
There is one fun fact about those trains, but I want to make it a little game. In those pictures, find one very unsual thing for us westerners. The winners gets a free ticket from Tashkent to Samarkand, worth 21 000 sums! 
I know I know!!!! You can send my ticket to my home address
