Abstract
A rail heating system is provided for heating railroad components such as railroad switch areas and electrified third rails. The heating system includes a side heater having a heating pad that has a flexible contact surface. A clip arrangement such as a spring steel clip is provided for securing the heating pads to the stock rail and pressing the contact surface into engagement with the rail. The contact surface of the heating pad is forced to conform to the shape of the contacted portion of the rail. Ground pan heaters may be used to keep areas of the switch that are not suitable for attachment by the side heaters, such as the switch rod, free from ice and snow.
