Regarding recent correspondence on guided buses versus light rail, I wondered if any authority has given serious consideration to conveyor systems as a possible solution to inner city transport.
It would seem to have many advantages. First, there are no emissions. Secondly, power consumed would be more proportional to the load.
Thirdly, such a system could be made very flexible and user friendly, allowing passengers to exit and enter at frequent points and use relatively narrow pavement width.
Might I suggest Edinburgh would be an ideal place for a trial!
