CBP TECHNOLOGY PRINCIPAL · WHEEL-RAIL INTERFACE

ELPA

Wheel and rail wear begins at the contact interface. ELPA's differentiation is to manage that friction mechanism directly, using application systems and materials designed around where and how the wheel contacts the rail.

FULL TECHNOLOGY OFFERING

WONROS® is a platform, not a generic rail-lubrication product.

ELPA separates trackside, onboard and marshalling-yard applications because gauge-face, top-of-rail and retarder problems are not the same.

CL-E1®

Trackside controlled application for friction-management material at defined rail contact zones.

TRACKSIDECURVESHOTSPOTSCONTROLLED DOSING

i-ROCK®

Onboard compressed-air application route for vehicle-mounted friction management.

ONBOARDCOMPRESSED AIRFLANGE / TOP OF RAIL

DRYproANNSYS®

Onboard airless/contact application architecture where the vehicle or operating environment favors a different delivery mechanism.

ONBOARDAIRLESSTRAM / METRO

BREMEX ANNSYS®

Specialized friction-management route for hump-yard retarders and marshalling-yard mechanisms.

MARSHALLING YARDRETARDERNOISE / WEAR

CAPABILITY MAP

The system and the material must be selected together.

Trackside application

Treat a known hotspot from fixed infrastructure.

Onboard application

Carry the treatment with the vehicle across a route.

Marshalling-yard treatment

Address retarder-specific friction, wear or noise.

Composite materials

DBM-KL, DBM-50, DBM-ToraX and related materials belong to their intended system.

Pilot & survey

Prove the mechanism at a defined location before broad rollout.

Lifecycle consumables

Plan material replenishment as part of the operating model.

FRICTION MANAGEMENT APPLICATION HELPER

Match the friction problem to the application point and operating constraints.

Friction modification can affect traction and braking. It requires controlled validation.

OBJECTIVE

ADHESION / BRAKING CONSTRAINTS

GUIDED SELECTION

Where is the friction problem actually occurring?

Location and contact mechanism come before product name.

CL-E1® trackside route

Use a fixed system when the problem is concentrated at repeatable locations and infrastructure installation is practical.

Track geometry, traffic, climate, application zone, material, adhesion/braking envelope and monitoring plan must be confirmed before deployment.

WHY THIS PRINCIPAL?

Friction management acts upstream of wear repair.

Grinding wheels and rails repairs consequences. Friction management can influence the contact mechanism that contributes to some wear and noise, but only when material, dosing and location are engineered without compromising traction or braking.

Problem location	ELPA route	Key distinction
Fixed rail hotspot	CL-E1®	Infrastructure treats every passing vehicle
Vehicle-mounted treatment	i-ROCK® / DRYproANNSYS®	Treatment travels with the fleet
Retarder / hump yard	BREMEX ANNSYS®	Different friction mechanism from ordinary wheel-rail contact
Broad rollout	Survey + pilot first	Measure effect before scaling

PROJECT EXPERIENCE

Current relationship is established; Indonesian deployment should be earned through a controlled pilot.

Principal relationship

CBP × ELPA · Slovenia

CBP and ELPA have a signed commercial relationship in the current portfolio. No Indonesian delivered WONROS® project is presented here without evidence. The website therefore emphasizes engineering mechanism, pilot design and measured outcomes rather than invented local references.

WHAT CBP ADDS

CBP turns a wear/noise complaint into a measurable pilot.

01 · Identify hotspotLocation, curve, rail, vehicle and complaint pattern.

02 · Define mechanismGauge face, top of rail, flange or retarder.

03 · Select system + materialApplication hardware and composite material are one solution.

04 · Measure before scalingTrack wear, noise and operating effect under controlled conditions.
