Waverail is a tram style light rail operation which embodies the world's first truly sustainable road transport. It uses non-stop sling-swap technology resulting in transportation as fast and as high-capacity as a train at speeds suitable for on-road operation. Its high personnel costs - each railcar has adriver - are overcome by extraordinary savings in energy, capital and maintenance, giving it, especially in high volume application, a remarkable profitability.
