The tramway system has one or more steel rail tracks (fig.1,11) with at least one gas supply port 72 adjacent the tracks. One or more trams (fig.1,10) travel on the tracks, each having a flywheel 20 to store energy; a gas driven motor 18; a gas inlet duct 61 with a valve (fig.5,84) and one or more pressurised containers 60. The gas may be natural gas or compressed air. Preferably, a number of stationary trackside compressors 66 pressurise mains supplied natural gas, or air, to be stored in stationary storage tanks 68. The tram may have a compressor 62, the trams containers storing the gas at up to 20MPa. The power to drive the tram may be provided indirectly from the flywheel, the tram comprising either a hydrostatic pump and motor; or an alternator and traction battery driving one or more electric motors. The gas supply port may have an electrically activated valves 70, which only permit gas flow when connected and sealed to the inlet duct of a tram. Claims for trams having a source of fuel derived energy, or a compressed air motor are also included.
