Brilliant .... From the O2 at North Greenwich Peninsula to the Royal Docks on the other side of the Thames.The Emirates Air Line is a cable car link across the River Thames in London, England built by Doppelmayr with sponsorship from the airline Emirates. The service opened on 28 June 2012 and is operated by Transport for London. In addition to transport across the river, the service advertises "a unique view of London". The duration of a single crossing is ten minutes (reduced to five minutes in rush hour as the service speed is increased).The service, announced in July 2010 and estimated to cost £60 million, comprises a 1-kilometre (0.62 mi) gondola line that crosses the Thames from the Greenwich Peninsula to the Royal Victoria Dock, to the west of ExCeL London. Construction began in August 2011. The cable car is based on monocable detachable gondola (MDG) technology, a system which uses a single cable for both propulsion and support, used also on the metrocable in Medellín, Colombia. The MDG system is reportedly cheaper and quicker to install than a more complex three-cable system which would allow larger-capacity cars.
