Just a word of warning to anyone now contemplating moving luggage on the metro. The ramps being referred to are very steep, they rise at the same angle as the stairs, and have a very narrow stair portion between the ramps. Trying to manage your wheelie bags would be very difficult indeed and it is better to carry them.

These ramps exist all over the former Soviet Union and I think they are designed to help mums with pushchairs but I have rarely seen them used for this purpose. I cannot speak for Russia but in Kazakhstan babies tend to be carried rather than pushed. Try pushing a pushchair in the ice and snow and you’ll realise why!
