It is there and several trains stop there a day. There is no timetable, there are no ticket offices and no information either. Kind people suggested how to find the dispatcher and find out the schedule. We managed to leave this station in the direction of Kutaisi - The train costs a minute, the payment from the conductor is 2 times more expensive, but since the fare is not high, it's not scary. But it is better and safer to get by train from Tbilisi.
