Well, there you are. The running water sound, described in this thread,
sounds like, well, water that is running - trickling - flowing gently from
point a to point b. It's not a torrent, nor a gush, nor does it imply that
the water is in any particular hurry. It's a gentle sound of water on its
way from one part of the train to another, seemingly induced by the motion
of the train itself. As the train starts up and gathers speed away from a
station, you hear the water running past. As the train loses speed to enter
a station, you hear it running back again. It doesn't sound like much
quantity of water either. It just seems to gently make its way from one end
of the train to the other, while more running water comes along, and so on.

I don't think there was any on the Jubilee line train I took yesterday,
and I did listen! Most disappointing!
