text_A: The Greenway, a shared-use path, runs through Plastow. The route runs from Hackney Wick to Plaistow, and has unbroken sections between Hackney Wick and Stratford (passing through the scenic Queen Elizabeth Olympic Park), and between West Ham and Plaistow. Eastbound, the route runs towards Newham University Hospital, East Ham, Beckton, and Cycle Superhighway 3 towards Barking. The Greenway runs atop Joseph Bazalgette's Northern Outfall Sewer. It is a part of Transport for London (TfL)'s cycle network, numbered Cycleway 22.
text_B: Would a bike sharing system be feasible for The Greenway, since riders would (at worst) only have to dock their bike and then pick up another once or twice during the journey (if at all)?
YES.
