Design Principles:without mass productionDesign Principles:without mass production
Proven design concept The City Class tram from TRAM Power Ltd. Has world wide application. Innovative design COTS = “components off the shelf”.
Mass Produced: (COTS) reduces costs Low initial, low maintenance and low running
costs. The City Class tram is a highly efficient vehicle. Can compete with buses on operating costs. Matches light rail for speed and comfort.
