There are many examples on the web of what a trolley bus support system looks like. The drawings on the NGT website indicate little and give no measurements. The diagram above shows what it could, and probably will, be like. There is no hard information from the proposers of the NGT. The dimensions here are calculated on the height to accommodate a double-decker bus. The cute diagrams of traffic-free streets and gossamer cabling systems on the NGT website bear no relationship to the engineering and safety requirements and their visual impact.
