Rail and Switch Heating Products

What are railway switch snow and ice prevention products?

Railway switches are a critical component of safe, reliable railway operations. During winter months, snow and ice accumulation on railways can prevent switches from properly aligning and fitting. EHT Engineering offers a solution to railway freezing problems with its heating cable technology.

Various types of cable-type or rod-type electric heaters, known as resistors, are used to heat and prevent freezing of switches on railway and tram lines. Special heaters are designed according to different rail and switch types.

Rail Switch Heating with Heating Cables?

The self-regulating cable and scissor heating system is an innovative solution that automatically adjusts the power output to compensate for temperature changes, providing the exact amount of power needed to protect rails and scissors from freezing.

Rod resistors offer a robust, long-lasting, and durable flat MI (mineral insulated) resistor solution for critical railway infrastructure, even under the harshest winter conditions.

This system features MI (mineral insulated) resistors that provide powerful convective heat over a large surface area on the rail network to prevent ice formation and ensure the smooth operation of railway switches. The rod-type resistor heating system offers significant advantages;

A Critical Solution in Railway Safety: Smart Heating Systems Against Winter Conditions

Rail transport is one of the most reliable and sustainable methods of urban and intercity transportation. However, especially during winter months, heavy snowfall and freezing temperatures can cause serious disruptions to rail systems. Rail switches are among the most sensitive mechanical components that enable trains to change direction. Freezing, snow accumulation, or icing at these points can lead to train service stoppages, delays, and safety risks. At EHT Engineering, we offer safe and energy-efficient solutions specifically designed for railway infrastructure with our Rail Switch Heating Products, developed to ensure the smooth operation of rail switches throughout all four seasons.

What is a Rail Switch Heating System?

The railway switch heating system operates via electric heating cables mounted under or on the side surfaces of railway switches. This system prevents the moving parts of the switch from freezing and becoming clogged with snow, thus preserving its mechanical functionality. The heating cables are specifically shaped to fit the rail profile and are controlled by thermostats. If required, they can be integrated into automation systems for remote monitoring and management.

EHT Engineering's rail switch heating products are successfully applied in both urban rail systems (trams, subways) and intercity railway lines.

• Industrial intra-plant rail transportation systems
• Airport apron rail systems

These systems play a critical role in maintaining the functionality of railway switches during winter months, especially in regions with a continental climate.

Protection Against Winter Conditions

Rail switch heating systems provide effective protection against the following environmental risks:

• Freezing: Prevents the moving parts of the scissors from becoming locked by ice.
• Snow accumulation: Heating prevents snow from sticking to the track surface.
• Icing: Any layer of ice that may form on the track surface is melted.
• Mechanical failure: Engine and drivetrain failures caused by freezing are prevented.
• Departure delay: This prevents transportation disruptions that could occur due to switch malfunctions.

These features ensure both passenger safety and operational continuity.
