Re: CRRC trackless trams set for Perth trial
  Tony Galloway

These things are optically guided, having some buried guidance system defeats the purpose of being “trackless”. Hardly useful for something touted as “cheaper than trams because there’s no track”.

Primove was an induction based power supply system AFAIK, not a guidance system. It was intended for electric vehicles following a fixed route, not necessarily trams, and failed due to the inefficiency of induction compared to direct contact systems, and the improvement in battery technology since it was invented.

Anyway, it’s just another over-hyped guided bus, a solution in search of a problem.
