Night train Tbilisi Zugdidi

[Belteral]

Hi all!
I am planning a trip to Georgia in September and wishing to go to the Svaneti region.
To do so I'd like to take the Tbilisi Zugdidi night train, but currently there are no timetables and no mention of it running on official or unofficial websites.
Does anyone have info on the current status of this particular night train? And if it runs, how I can book it when the time comes?
Many thanks!

I did not find it in the official schedule either, seems like only the day train is running. Might have something to do with cuts in governmental subsidies (the night train was ridiculously cheap and mainly funded by the government).
