wheel flange lubrication system
NSP-WFL is a proven system. It is cleaner, simpler and less problematic than on-board spray or trackside systems, and far more durable than any other solid lubricant. READ MORE

About AW Solutions

At AW Solutions we help train operators solve wheel flange wear problems. As a company based in the heart of Poland, we have been introducing a dry, bio-based wheel flange lubrication system.

NSP-WFL solid sticks are primarily based on renewable resources, soy and corn. American scientists discovered that soy oils have excellent lubricating capabilities, are eco-friendly, biodegradable, and can be extensively used in railway industry.

Solid lubricants can help reduce flange wear, extending wheel sets life considerably.

NSP-WFL bio-based wheel flange lubrication system.

NSP-WFL reduces the coefficient of friction, minimizes wheels’ flange and rail wear, while saving fuel/energy and limiting noise. 

To improve the wheel-rail cooperation, system lubricates the most vulnerable areas of wear. Solid sticks are pressed against the wheel flange with spring. The thin coating is being passively transferred through rail to subsequent wheels. 

NSP-WFL solid lubricants are primarily manufactured from soy and corn, making them sustainable and better for the environment.

Our lubricants last thousands of miles more than competitive solid sticks.

Manufactured with highest diligence in the homeland of solid sticks.

Direction: Savings

NSP-WFL is the most efficient and reliable system of wheel flange lubrication. It is cleaner, simpler, and less problematic than on-board spray or trackside systems and our bio-based sticks last thousands of miles more than competitive lubricants.

Savings on flange lubrication


“At the moment, the fleet of Siemens INSPIRO vehicles that is operating on the Warsaw Metro lines is equipped with NSP-WFL solid stick wheel flange lubrication system offered by AW Solutions.”

SIEMENS Mobility Sp. z o.o.

“After a two-year period of use, we observed a considerable (about 40%-50%) decrease in the pace of the wear of wheel flanges compared to locomotives not equipped with the lubrication system.”

Rail Polska Sp. z o.o.

“We declare that, using solid stick wheel flange lubrication system [NSP-WFL] extended the longevity of wheel sets by nearly 50%.”

WISKOL Sp. z o.o.

“We declare that [NSP-WFL] solid sticks can be successfully used for wheel flange lubrication in locomotives’ wheelsets, diminishing thereby their wear.”

Freightliner PL Spółka z o.o.

“We have been using […] 300mm long applicators with interlocking soy sticks […] for over a year and we have been very pleased with the results with a marked reduction in wheel flange wear where the applicators have been fitted. We will be extending their use over the next few years.”

Ffestiniog & Welsh Highland Railways

“Performed observations revealed much lower consumption of the [NSP-WFL] sticks for lubricating the wheel flange as against to currently used. ”

DB Cargo Polska S.A.

“The applied layer of lubricant stays resistant to weather conditions and it is not removed from the metal surfaces after precipitations. The soybean oil-based sticks characterize themselves with lower wearing at steel wheels surfaces than the graphite sticks.“

DCT Gdańsk SA

“The consumption of [NSP-WFL] solid lubricants is 46.2 % lower compared to currently used”

Express Rail Link Sdn Bhd

“Conclusions: the consumption of [competitive] solid lubricants is 2.6 times greater than [NSP-WFL].”

JSC „Lietuvos geležinkeliai“

“From above, it emerges that on locomotives subjected to observation, the wear of […] soy sticks was about 50% lower than of the competing provider.”


“In the following weeks, wear of the [NSP-WFL] sticks were already two times lower and amounted to approx. 15-20mm per week (10mm / 4300km).”

„PKP Intercity” Spółka Akcyjna

“Performed operations have shown a few times lower consumption of the lubricant for wheel flanges (about 20mm/10 000km) compared to the previously used.”

"Przewozy Regionalne" sp. z o.o.

“Given this, the consumption of [NSP-WFL] lubricating sticks was twice lower than the consumption of the currently used lubricating sticks.”

Szybka Kolej Miejska Sp. z o.o.

“As the results were good, from the technical and economical point of view, FERTAGUS continues to use this product until today. “

Fertagus: Travessia do Tejo, Transportes S.A

“Based on the test results and price, we have decided to use soy sticks on our fleet.”
