Train Baku-Sheki? + itinerary tips

Hi everyone.

I'm trying to figure out if the night train between Baku and Sheki is running again? All the travel blogs say it is discontinued but when i check the ADY ticket website it seems the nighttrain runs? Anyone that can give some clarity?

Im planning to travel the Caucasus this summer, looking to spend 5 days in Azerbaijan. Would love to do Baku - Sheki - maybe a dayhike in Laza, is this reasonable or would it not be doable with all the travel inbetween (you see how the nighttrain can be an important factor here haha) ? Any other suggestions for areas to do dayhikes in are also welcome! Thanks a million
