Custom rail solutions

Delivering customised solutions for metro, inter-city, high-speed and freight rolling stock, Norgren collaborates with many of the industry’s key organisations. From specialist OEMs to demanding train operators and busy maintenance teams, Norgren’s portfolio of innovative, robust, and compliant pneumatic control product solutions for the rail industry is built on a strong heritage, industry knowledge and technical expertise that addresses the unique operating challenges the industry faces.

All of Norgren’s rail-specific projects are based upon exact customer needs and the delivery of a customised solution providing the solutions maintenance professionals and rail engineers require. This includes control solutions that support essential rolling stock systems, including compressed air dryers, braking control components, door controls, pantograph and coupling control, water control and secondary suspension systems. All system technologies are designed for compliance with exacting rail industry standards:

EN 61373 Category 1 class A and B vibration resistance
EN 45545-2 Fire and Smoke
Temperatures ranging from -40°C to +85°C (-40°F to +176°F)
Voltage tolerances of +/- 30%

Addressing a challenging operating environment where excessive temperature ranges, voltage tolerances, vibration challenges and fire and smoke dangers are continually present; Norgren’s wide-ranging solutions deliver consistent long-term performance, lower maintenance costs and are at the cutting edge of innovative thinking.

Secondary Suspension System Control

Valves for accuracy, long-life and operational efficiency.

Accurate

The deterioration over time of control valve accuracy is a key industry issue associated with the long-term performance of secondary suspension systems. Norgren is leading the way in solving a problem prevalent across control solutions, which leads to increased costs and impacts rolling stock availability.

Long Life

Norgren’s mechanical levelling, average and compensation, over-height, and special electronic proportional levelling valves, provide extended accuracy over a longer period, meaning industry-standard refurbishment intervals of around five years can be extended to around eight to ten years.

Efficient

Tested to meet relevant compliance standards, Norgren’s range of valves offer longer time periods between required maintenance and adjustment, ensuring reduced pressure on resources.

Pantograph Control

Control innovation to deal with operating challenges.

Reliable

The environment in which train pantograph control systems operate presents ongoing challenges. Positioned on train roofs and exposed to extreme weather variances and ever-higher travelling speeds, the components that make up the pantograph control system must guarantee reliability and performance.

Robust

From a specially created modular control assembly that can reduce installation and commissioning times, to an ability to withstand both high and low operating temperature environments - as well as rigorously evaluated and validated for operation on high-speed trains - the robust characteristics of Norgren’s pantograph control solutions are proven.

Long Life

From proportional valves, pressure regulators and pressure switches and innovative ‘auto drop down’ and ‘over-reach’ control functions, pantograph control can be assured for the long-term.

Braking Control

Braking components to be relied upon.

Safe

The critical importance of train braking systems is non-negotiable and with it the need for all braking control systems and components to perform to the highest standards to ensure passenger safety.

Proven

Norgren’s industry-proven components – including solenoid valves, regulators, and pressure switches – are intrinsic elements of a successful and ultra-reliable train braking control system.

Long Life

Offering flexible mounting, a wide temperature range, resistance to vibration, high tolerance, and surge suppression, as well as long performance life, Norgren’s components are widely specified across the global rail sector.
