This green strip between buildings off Rydal Crescent has beneath it a Metropolitan Water Board 42" and 48" main; see description of this main http://middlesexcountycouncil.org.uk/index.php?option=com_content&task=category§ionid=9&id=17&Itemid=35 in Nick Papadimitriou's Middlesex County Council website. The main runs from Hampstead Garden Suburb to Hampton Wick. Here it has a bridge under the Central Line. Thanks to John Webb for telling me that this is the line of a water main.
