I am wondering how badly affected the train service between Ankara and Kars is by winter weather. I hope to take the train through to Tbilisi (if it is running by then) in mid December but expect that it gets a bit cold traversing Turkey.

For Ankara Kars train, winter caused sometimes delays, nothing worse.
The Ankara-Baku train will most probably -and hopefully- be working by December 2018. Azerbaijan Railways announced an opening before summer.
