Oh! this is a very interesting fact, @tattoodjay .I would never have thought that this descent into the subway, if you do not read the sign :))
these entrances look very unusual for the subway, but I liked that you can go down the Elevator instead of the usual escalator for us.
Sometimes escalators tire me too much because some stations in St. Petersburg are very deep , if the branch passes under the Neva. Therefore, the descent on the escalator takes a long time and the descent on the Elevator in this case I would be faster.
Thank you for interesting photos and useful information. Now I'll know about it :))
