I used to commute on the Docklands Light Railway. It can be quite a stunning journey with views across the old docks to one side and sweeping sections of the Thames swinging into view on the other.
The stations themselves are stunning pieces of design, utilitarian concrete, steel, glass and mesh. Many of them are supported on pylons 30 foot above the street.
