Our innovative range of onboard curved rail lubricants are designed for application via onboard wheel flange lubrication systems, delivering targeted lubrication to the gauge face of the rail to protect the wheel / rail interface. 

The lateral forces exerted between the wheel flange and rail place particular strain on curved sections of track, and without effective lubrication this impact can be costly. Research from Sid & Wolf in America found that ineffective lubrication led to wear and friction at the wheel-rail interface, costing more than $2 billion each year to maintain. 

In 2004, more than $10 billion was spent on rail transit system maintenance due to poor lubrication in the USA. If lubrication is not efficient or continuous, then the coefficient of friction varies, often resulting in extensive and costly wear in badly lubricated areas.

Onboard Spray Lubricant

EcoCurve Onboard is a high performance, innovative gauge face lubrication solution designed for application via on-board wheel flange lubricators / ‘spray equipment’. Formulated to meet the unique challenges of onboard application and ensure optimal protection at the wheel/rail interface.

Specifically developed for use in high speed rail metro or light rail applications, our EcoCurve Onboard HS curved rail lubricant offers impressively low fling-off performance. Designed for application via on-board wheel flange lubricators, this ‘sprayable’ lubricant delivers precise lubrication to the wheel, and rail gauge.

Onboard Stick Lubricant

Claretech EcoStick WFS an environmentally friendly wheel flange stick lubricant, compatible with stick lubrication systems that are mounted to the train’s bogie to continually apply precise lubrication to the wheels and reduce wear at the wheel/rail interface.

Case Study

The West Midlands Metro had ongoing issues with noise complaints, particularly where the track ran close to urban areas like Birmingham's City Centre.

Having trialled a range of alternative wheel flange greases with little success, the Track Maintenance Manager initiated a trial of EcoCurve Onboard in their CAF Urbo3 trams Bijur Delimon onboard spray systems.

“We compared our incumbent wheel flange stick lubricant with this soy-based stick in a comparative field trial over a 10 month period on one of our rolling stock where there are 12 applicators fitted. Over this period the trial found that we used the equivalent of 3 sticks per train / per month of the Eco Stick, compared with 21.6 sticks per train / per month of the molybdenum-based stick we had been using. The savings opportunity was overwhelming.”
