Train wheel measurement intelligence

Readings typed in by hand or uploaded from a CALIPRI, kept as one record per wheelset. See the whole fleet, the wheels closest to their limits first, and how wear is trending across every depot.

See what your measurements say

Real Wheel Hub screens, shown with a demo fleet. Every figure comes from CALIPRI exports or readings typed in by hand, judged against the measurement plan's own bands.

The whole fleet at a glance

Every measured wheel counted by the band its plan puts it in, led by the sets with a wheel in the most severe one. Depots sit side by side, so you can see where readings concentrate.

Every reading on its wheel

Each inspection laid out as the train: every wheel in its car, bogie and axle position, coloured by the band its measurement plan sets. A bogie or side that stands out shows at a glance.

Every CALIPRI scan, drawn as measured

The profile the CALIPRI recorded, unsmoothed, as a dimensioned cross-section. Each dimension carries its value in millimetres and the colour of its band.

Wear over time, and its forecast

Each dimension trended across every inspection of the wheel. Hand and CALIPRI readings share one line. With enough history, a forecast carries the line on, with a widening range and a confidence rating. A forecast, not a verdict.

Also in Wheel Hub

Wheel lifecycle

Each physical wheel keeps its identity through machining, switches, and replacement — history included.

Built for teams

Role-based access for operators, supervisors, and admins keeps everyone on the data they need.

Three steps from the wheel to the fleet

No integration project. No new hardware. Just the readings you already take.

1

Measure with CALIPRI or by hand

Run your inspections as you do today, with a CALIPRI or with hand gauges. WheelHub works from your own measurement plans.

2

Upload the export, or type the readings in

Drop in the CALIPRI XML and WheelHub places every car, bogie, axle and wheel from your plan. Or type the readings in, or fill in the CSV template and import it.

3

See fleet health

Dashboards, tolerance flags and wear trends are ready as soon as an inspection is saved.

Tell us how you measure

WheelHub reads CALIPRI exports, and readings typed in by hand or filled into its CSV template. Measure with something else? Tell us what you use. We read every reply, and it helps decide what we support next.
