05 / RESTORE & MAINTAIN

Treat the cause, restore the asset, and extend useful life.

Some railway assets do not need replacement yet. They need controlled machining, surface treatment, friction management or a repeatable maintenance process.

THE CUSTOMER QUESTION

Can this wheel, rail or operating interface be restored or managed before replacement becomes necessary?

THE CBP ROUTE

Measure the condition, choose the intervention and verify what changed.

PRODUCT ROUTES

Four maintenance routes acting at different parts of the railway lifecycle.

KOLTECH restores wheel geometry, Vossloh treats and inspects rail, ELPA manages the wheel-rail contact, and ISTOBAL makes fleet washing a controlled depot process.

01

Wheel Reprofiling

KOLTECH · TUP / TUU / VIDIgo

Measure wheel wear, machine the profile back into shape and verify the result.

Choose it when: usable wheel material remains but geometry has moved out of condition

VIEW PRODUCT ROUTE
02

Rail Grinding, Milling & Inspection

Vossloh · HSG-city / VTM-compact / SoniQ

Choose preventive grinding, corrective milling or internal inspection from the actual rail condition.

Choose it when: the network needs a rail-lifecycle intervention rather than reactive replacement

VIEW PRODUCT ROUTE
03

Wheel-Rail Friction Management

ELPA · WONROS®

Control friction at the wheel-rail interface using dedicated trackside, onboard or yard systems.

Choose it when: wear, squeal or contact conditions justify an engineered friction-management program

VIEW PRODUCT ROUTE
04

Train Washing

ISTOBAL · HW'TRAIN / HW'PROGRESS2 RS

Turn external train cleaning, water management and service into a repeatable depot process.

Choose it when: fleet volume and cleaning requirements justify a dedicated railway wash facility

TECHNOLOGY PRINCIPALS

Different problems need different specialists.

These are specialist product ecosystems with equipment, software, consumables and lifecycle support, not commodity machines.

WHAT TO DECIDE FIRST

Start with the lifecycle outcome that needs to be protected.

The buyer should see what is preserved: wheel life, rail life, controlled contact conditions, or predictable fleet-cleaning capacity. CBP then connects the technology to measurement, workflow, consumables and long-term service.

NEED HELP CHOOSING?

Describe the railway problem in ordinary language.

CBP will narrow the technology route before discussing exact configuration.
