Abstract
A water cooling loop is connected to cool an engine of a railway car or the like and includes a heat exchanger. A system for heating a compartment includes a pump for pumping water to heating elements. The water from the pump is selectively pumped through a first path which includes the heat exchanger or through a second path which by-passes the heat exchanger dependent upon the temperature condition inside the car.
