Why take a long trip in search of Mother Nature – when we can bring her downtown for you? After all, we expect mass rapid transit to be not only environmentally friendly, but that it also makes life in the city a little more worth living. Owing to its appealing optical impression and its favourable environmental characteristics, the RAILONE "Green Track" is an outstanding choice for mass rapid transit. The ATD-G ballastless track system has been designed for applications for trams and surface commuter railways in downtown areas. The ATD-G is primarily characterized by bi-block concrete sleepers directly supported by an asphalt layer. A lateral-force base support effectively secures the track span. The system can be covered by turf or sedum plants, in various heights.
