The Importance of Correct Lubricator Selection and Placement in Gauge Face Lubrication for Rail Wear and Noise Reduction
In the railway industry, correct lubrication is crucial to ensure safe and efficient operations. One area that requires special attention is gauge face lubrication, which involves applying grease to the contact surface between the train wheel and the rail gauge face. This process helps reduce rail wear and noise, contributing to a smoother and quieter ride for passengers.

The Role of Lubricators
A gauge face/check rail wayside lubricator system is designed to automatically apply the right amount of grease at regular intervals. This ensures that the lubrication is consistent and eliminates the need for manual application, which can be time-consuming and labour-intensive. The correctly selected and placed lubricators are key to achieving optimal results in gauge face lubrication.
The Right Selection of Lubricators
When selecting a lubricator for gauge face lubrication, several factors need to be considered. These include lubricating one curve or several from one lubricator, the type of rail profile, type & frequency of traffic, vandalism risks, pick up and carry down of grease. For example, curved rails require specialised greases that can withstand higher stresses and provide better adhesion. Similarly, high-traffic areas may require more frequent greasing to maintain the desired level of lubrication.
The Importance of Location & Placement
Where a lubricator is placed on the track also has a significant impact on its effectiveness. A competent person should conduct a thorough site assessment to determine the optimal placement based on factors such as curvature (radius), gradient, and track conditions. For example, placing a lubricator in the incorrect location on the rail can result in insufficient grease pickup & coverage, leading to increased friction and wear.
The Quality of Grease
Another critical factor in gauge face lubrication is the quality of the grease used. Using high-quality greases such as RS Clare’s curved rail greases can significantly improve performance and reduce maintenance costs. These greases are specially formulated to withstand extreme pressures and offer long-lasting lubrication, even in harsh environments.
In summary, right selection and placement of lubricators are crucial for effective gauge face lubrication. Considerations must be given to factors, such when selecting a lubricator for gauge face lubrication, several factors need to be considered as previously explained. By ensuring these aspects are addressed, rail operators can reduce wear and noise, resulting in a smoother and more enjoyable experience for passengers. As always, it is essential to have a competent person conduct the relevant assessments and follow industry best practices to ensure safe and efficient railway operations.
