PLC-Controlled Switch Heating for ProRail: A Technical Breakthrough

RJ Kross has designed and implemented an advanced, PLC-controlled switch heating system for critical railway junctions of ProRail. This technology is essential for guaranteeing operational continuity during the winter months.

The Challenge: Switch Freezing

At temperatures below freezing and under specific humidity conditions, switches can freeze, leading to delays and potentially dangerous situations. Traditional systems often only react once the problem has already occurred.

Our Proactive Solution

Our system continuously monitors temperature and humidity directly on the rails. Using advanced PLC control (Programmable Logic Controller), it anticipates freezing conditions and activates the heating elements proactively.

• Real-time monitoring of rail conditions
• Automatic, logic-based activation
• Energy-efficient through targeted heating
• Reliable operation under all winter conditions

Result for ProRail

The implementation of this system at crucial junctions has led to a significant decrease in switch-related failures in winter. The operational continuity of the railway network is thereby ensured, which is vital for Dutch infrastructure.

"The PLC-controlled approach by RJ Kross enables us to act preventively, rather than reactively. This is a fundamental improvement in the management of our winter readiness."

This case study underscores our commitment to innovative railway engineering that provides practical, reliable solutions for complex infrastructure challenges.
