Two new snow-melting systems utilizing natural heat sources have been studied from a viewpoint of the conservation of energy and resources: (1) a system assisted with engine heatpumps and thermal storage tanks. (2) a system coupled with aquifer as a thermal storage where the solar energy from the the track is stored in summer and is pumped up in winter. These systems are able to consume much less fuel than the conventional system which sprinkles the heated water of about 15 Cel in boiler to remove snow deposit. From a point of view of short term investiment, the employment of engine heatpump is realistic. Since the large thermal storage tank is quite expensive, the use of aquifer is very promising.
