Does anyone have any pointers as to wheelchair access on the Moscow Metro? I read on a webpage that some new stations opened in 2011 that are 'accessible' but it didn't say which they are.

I understand the Metro is not feasible for getting from A to B in a wheelchair but I would be interested in doing a trip on it from an accessible station even it is only "there and back" getting off again at the station which I initially boarded.
