Emphasis mine. Important point here, for anyone who hasn't done a metro transfer to one of the main railway stations to catch an Aeroexpress or long distance train. There are quite a few spots in the Moscow metro where there are short flights of stairs to transfer from one line to another... stairs - not escalators. (Some spots have escalators, but not all.) Do keep this in mind if you have a suitcase that you're lugging around, especially if it's during rush hour. A taxi might not be a much better option given traffic (and how expensive it'll end up being). Certainly does make a two-ticket transfer at the airport much more appealing.
