RESTORE & MAINTAIN / WHEEL-RAIL FRICTION

Manage friction before it turns into wear and noise.

ELPA’s WONROS® platform treats the wheel-rail contact as a controllable maintenance interface. The portfolio covers trackside, onboard and marshalling-yard applications with dedicated composite materials.

In practice: apply the right friction-modifying material at the right wheel-rail contact zone, then measure whether wear or noise improves.

Slovenia · Wheel-rail friction management

WONROS® trackside, onboard and marshalling-yard systems plus proprietary friction-management materials and pilot engineering.

PRODUCT OPTIONS

WONROS® is a platform with separate product families for different contact problems.

The system should never be reduced to ‘rail grease’. ELPA uses controlled application systems and dedicated composite friction modifiers for specific wheel-rail mechanisms.

01

CL-E1®

Trackside application system for controlled friction management on rails.

Best for: curves, station approaches, metro, tram and mainline hotspots

02

i-ROCK®

Onboard compressed-air application of friction-management material.

Best for: vehicle-mounted flange or top-of-rail treatment

03

DRYproANNSYS®

Onboard airless/contact application architecture.

Best for: tram and metro vehicles where low-air-demand installation is useful

04

BREMEX ANNSYS®

Specialist treatment system for hump-yard retarders.

Best for: marshalling-yard noise and wear problems

05

DBM-KL / DBM-50 / DBM-ToraX

Dedicated composite friction-management materials for the corresponding systems.

Best for: recurring lifecycle material supply

06

Site Survey & Pilot

Engineering, safety validation and measured field trials before broad deployment.

Best for: new networks and Indonesian qualification

HOW IT WORKS

Identify the friction problem before choosing the application system.

01

Locate the mechanism

Gauge face, top of rail, flange, retarder or another defined contact zone.

02

Choose trackside or onboard

Match the application method to the network and vehicle.

03

Apply controlled material

Dose the dedicated composite material where it is needed.

04

Measure the effect

Track wear, noise and operational behaviour before expanding the program.

WHY THIS MATTERS

Repairing wear later is more expensive than controlling the mechanism that creates it.

Wheel and rail damage starts at the contact interface. A controlled friction strategy can address the mechanism upstream, but it must remain inside the required adhesion and braking envelope.

Before: wear and noise are treated mainly after they appear.

After: the wheel-rail interface becomes an engineered part of lifecycle maintenance.

CBP'S ROLE

The product is only useful when it fits the real railway job.

CBP works with ELPA in Slovenia to define hotspots, pilot conditions, application method, material route, installation and lifecycle consumables before broad deployment.
